Amplifier With Active Bias Compensation And Method For Adjusting Quiescent Current
US Patent:
6046642, Apr 4, 2000
Filed:
Sep 8, 1998
Appl. No.:
9/149520
Inventors:
Daniel C. Brayton - Covina CA
Jeffrey K. Jones - Tempe AZ
Robert S. Kaltenecker - Mesa AZ
Bill Tabano Agar - Chandler AZ

Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H03G 130
US Classification:
330296
Abstract:
An active bias compensation circuit (110) senses a quiescent current flowing in an amplifier (130) and adjusts the quiescent current to maintain an optimal DC biasing of the amplifier (130) over a wide range of factors, e. g. , temperature variation, process variation, history of the amplifier (130), etc. The compensation circuit (110) includes two transistors (101, 102) forming a difference amplifier. A sensing voltage proportional to the quiescent current and a reference voltage are applied to the base electrodes of the two transistors (101, 102), which generates a bias signal in response to a difference between the sensing voltage and the reference voltage. The bias signal adjusts the quiescent current in the amplifier (130).
High Frequency Linear Amplifier Assembly
US Patent:
5142239, Aug 25, 1992
Filed:
May 20, 1991
Appl. No.:
7/702490
Inventors:
Daniel C. Brayton - Covina CA
Ngai-Ming Lau - Rowland Heights CA
Ngai-Ming Lau - Rowland Heights CA
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H03F 326
US Classification:
350 66
Abstract:
A wide bandwidth linear amplifier (10) that has an operating band in excess of 1 GHz mounts the high power dissipating components (11) of the amplifier (10), and the components 917, 18) that control the high frequency gain and stability of the amplifier (10) onto a daughter board (32) that has a high thermal conductivity. The daughter board (32) and the remaining circuit components (21, 22, 23, 24, 26a, 26b) are then mounted on a mother board (31) that has a lower thermal conductivity. The assembly (30) reduces the circuit's parasitic inductance (46, 47, 48, 49) and parasitic capacitance (51, 52), and provides unconditional stability at high frequencies.
