Mar 19, 2002
Appl. No.:
10/102501
Inventors:
Jun Chen - Allen TX
Xiaoyu Xi - Plano TX
Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
G05F 140
US Classification:
323280, 323281, 323274
Abstract:
The low dropout voltage regulator (LDO) circuit with improved power supply rejection ratio includes: a first amplifier having a first input coupled to a reference voltage node V ; a second amplifier having an input coupled to an output of the first amplifier ; a pass transistor having a control node coupled to an output of the second amplifier ; a feedback circuit and having an input coupled to the pass transistor and an output coupled to a second input of the first amplifier ; an inverting gain stage coupled to the input of the second amplifier ; and a high pass filter , and coupled between a power supply node and a control node of the inverting gain stage. The circuit uses the high pass filter , and and inverting gain stage to feedforward the power supply ripple into the LDOs control loop which counter-acts the impact of the supply ripple on the output node V.

Bandgap Voltage Reference Insensitive To Voltage Offset

US Patent:
6690228, Feb 10, 2004
Filed:
Dec 11, 2002
Appl. No.:
10/316340
Inventors:
Jun Chen - Allen TX
Siew Kuok Hoon - Dallas TX
Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
G05F 302
US Classification:
327538, 327541, 327542, 323313
Abstract:
A bandgap reference circuit. The circuit includes a first current mirror having a first mirror transistor and a second mirror transistor. A holding circuit has an output adapted to control a current though the first current mirror by operating to maintain substantially equal the voltages at a first input thereof and at a second input thereof. A first bipolar transistor having an emitter, a base, and a collector, wherein the area of the emitter thereof has a predetermined size, is arranged to conduct a collector current from the first mirror transistor. A second bipolar transistor having an emitter, a base, and a collector, wherein the area of the emitter thereof has a size that is proportional to the size of the emitter area of the first bipolar transistor, is arranged to conduct a collector current from the second mirror transistor, the base thereof being connected to the collector thereof. A first resistor is provided, in series with the collector of the second bipolar transistor and the second mirror transistor. The base of the first bipolar transistor is coupled to a common connection node of the first resistor and the second mirror transistor to substantially reduce the effects of offset error in the holding circuit.

Threshold Voltage Extraction Circuit

US Patent:
6844772, Jan 18, 2005
Filed:
Dec 11, 2002
Appl. No.:
10/316495
Inventors:
Siew Kuok Hoon - Dallas TX, US
Jun Chen - Allen TX, US
Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
G05F 110
US Classification:
327541, 327539, 327543, 323315, 323316
Abstract:
A threshold voltage extraction circuit. The circuit includes a first current mirror having a first transistor and a second transistor. A holding circuit has an output adapted to control a current though the first current mirror by operating to maintain substantially equal the voltages at a first input thereof and at a second input thereof. A third, MOS transistor having a source and a gate, and a resistor circuit, together adapted to generate a voltage which is a multiple of a source-gate threshold voltage of the third transistor, are coupled to the second transistor and to the first input of the holding circuit. A fourth, MOS transistor coupled to the first transistor and to the second input of the subtracting circuit through a second resistor circuit is adapted to generate a threshold voltage across the second resistor circuit, by the operation of the holding circuit. A second current mirror coupled to the first current mirror is adapted to cause a current to flow through a third resistor circuit that corresponds to the current through the first current mirror to thereby provide an output voltage corresponding to the threshold voltage.

Low Drop-Out Voltage Regulator With Power Supply Rejection Boost Circuit

US Patent:
6897637, May 24, 2005
Filed:
Dec 9, 2002
Appl. No.:
10/314931
Inventors:
Jun Chen - Allen TX, US
Siew K. Hoon - Dallas TX, US
Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
G05F001/618
US Classification:
323274, 323303
Abstract:
A low drop-out voltage regulator uses a voltage subtractor circuit to form a power supply rejection boost circuit. The voltage subtractor is inserted between the pass element and the amplifier of the low drop-out regulator. The voltage regulator circuit includes a pass element coupled between an input node and an output node; a voltage feedback circuit and coupled to the output node Vo; an amplifier having an input coupled to the voltage feedback circuit; and a voltage subtractor having a control node coupled to an output of the amplifier , an output coupled to a control node of the pass element , and an input coupled to the input node. The boost circuit improves supply noise rejection performance significantly without adding much complexity to the regulator system. The boost circuit is simple and consumes negligible silicon area and power.

Regulated Cascode Current Source With Wide Output Swing

US Patent:
6903539, Jun 7, 2005
Filed:
Nov 19, 2003
Appl. No.:
10/716958
Inventors:
Jun Chen - Allen TX, US
Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
G05F003/16
US Classification:
323315, 327530, 327362
Abstract:
System for a current source with enhanced output impedance. A preferred embodiment comprises a cascode current source arranged in a current mirror configuration (such as current source ) with a pair of level shifters arranged in a source-follower configuration (such as level shifters and ).

Compact Frequency Doubler/Multiplier Circuitry

US Patent:
6967508, Nov 22, 2005
Filed:
Mar 4, 2004
Appl. No.:
10/794833
Inventors:
Jian Zhou - Plano TX, US
Jun Chen - Allen TX, US
Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
H03K023/54
US Classification:
327122, 327116
Abstract:
The frequency doubling circuit and method provides an output signal with stable frequency and a 50% duty cycle. The frequency of the output signal is two times a frequency of the input signal. The circuit only requires four comparators, eight small capacitors, and some switches and transistors for frequency doubling applications. With the help of feedforward structure, the circuit has an almost-instantaneous response. The performance of the provided frequency doubling circuit and method is independent of the frequency and duty cycle of input signal, power supply voltage, temperature, and process variations.

Method And System For Providing Virtual Access To Information Distributed Across Heterogeneous Catalog Servers

US Patent:
6970840, Nov 29, 2005
Filed:
Oct 6, 2000
Appl. No.:
09/680676
Inventors:
Jin Yu - Mountain View CA, US
Jun Chen - Sunnyvale CA, US
Hseuping Chen - Milpitas CA, US
Assignee:
Martsoft Corporation - Santa Clara CA
International Classification:
G06F017/60
US Classification:
705 27
Abstract:
A method and system for providing virtual access to product/service information distributed across heterogeneous catalog systems is disclosed. The method and system include subscribing a first catalog server to at least a portion of the information stored on one or more remote catalog systems, thereby creating a subscribing catalog server. Thereafter, a replication process is performed to synchronize information on the subscribing catalog server with the subscribed information on the remote catalog systems. A user may then use the subscribing catalog server to search and browse the synchronized information, thereby providing one site for viewing information from multiple catalog servers.

Switching Mode Power Conversion With Digital Compensation

US Patent:
7042200, May 9, 2006
Filed:
Apr 7, 2003
Appl. No.:
10/408530

Keith Kunz - Bryan TX, US
Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
G05F 1/40
US Classification:
323283
Abstract:
The present invention provides improved line and load regulation of a switching-mode power converter () without requiring additional capacitors (), either internally or externally, to stabilize the control loop. The present invention can provide this by integrating a digital compensator () with the pulse-width modulator (“PWM”) of the switching-mode power converter. Such a compensator () can include comparators ( and ), digital circuits (), and resistors (, and ).
