A drive circuit that produces an over-voltage signal and protects circuit components from the over-voltage signal (i. e. , such that circuit components operate within process specification limits). A photosensitive pixel cell can be driven by the drive circuit. Use of the drive circuit increases dynamic range of the pixel cell and reduces âghost images. â Control logic selectively passes an over-voltage signal to individual rows of a 2-D pixel array.

A pixel column amplifier architecture creates a reduced noise differential image signal from an pixel sensor array. The pixel column amplifier architecture comprises a first double sampling (DS) circuit and a second DS circuit that has the same configuration as the first DS circuit. An image signal containing a combination of noise components created on a substrate is coupled to the first DS circuit. A reference image signal, held in a reset state, represents the noise component of the image signal and is coupled to the second DS circuit. Further, a reference voltage source is coupled to a reference input of both the first DS and the second DS circuits. The first DS circuit provides the first side of the differential image signal, and the second DS circuit provides the second side of the differential image signal.

A ground referenced pixel reset circuit is disclosed. The ground referenced pixel reset circuit supplies a pixel with a reset signal such that when the reset signal is asserted high, the reset signal is at a ground referenced reset voltage independent from a supply voltage. The pixel includes a photosensor, such as a photodiode, that is coupled to a ground having a same potential as the ground of the reference voltage supply. In this manner, noise caused by fluctuations in the supply voltage is reduced.

A method of sampling image signals generated by pixel circuits of an active pixel sensor (APS) image sensor. The APS image sensor supports a normal mode of operation and a sub-sampling mode of operation. The method includes providing a plurality of column amplifiers. A row of pixels circuits to sample is selected. Image signals from each pixel circuit in the selected row are routed to a different one of the plurality of column amplifiers when the APS image sensor is in the normal mode of operation. Image signals from a plurality of the pixel circuits in the selected row are routed to one of the plurality of column amplifiers when the APS image sensor is in the sub-sampling mode of operation.

An active pixel sensor (APS) image sensor comprises an array of pixel circuits corresponding to rows and columns of pixels, a plurality of amplifiers that buffer signals output by the array of pixel circuits, and a plurality of sample and hold circuits that read the buffered signals. A routing mechanism is positioned between the array of pixel circuits and the plurality of amplifiers. A controller selects a set of the pixel circuits for sampling and is configured to control the routing mechanism to couple each pixel circuit in the set to a different one of the amplifiers during a normal mode of operation and to couple each pixel circuit of a subset of pixel circuits in a first set of pixel circuits to a different amplifier of a first subset of the amplifiers, to couple each pixel circuit of a subset of pixel circuits in a second set of pixel circuits to a different amplifier of a second subset of the amplifiers, and to connect the amplifiers of the first and second subsets of amplifiers in pairs to a common one of the sample and hold circuits during a sub-sampling mode of operation.

A pixel circuit includes a silicon substrate having a photodiode that converts light intensity into a voltage signal and two metal layers disposed on the substrate having a pixel control circuit. The first metal layer includes a row trace and a reset trace and the second metal layer includes a column trace and a voltage supply trace. The row trace carries a signal that activates a switch for coupling the photodiode to the column trace during a readout phase and clears the voltage at the photodiode during a reset phase. The column trace interfaces with a signal capture circuit in a CMOS array of pixels for capturing a digital image that corresponds to each voltage level at each photodiode.
