Patent ID: 8035073

Claim:
A method for controlling amplification of signals read from an imaging circuit, comprising: receiving first input signal representing variations in pixel values from the imaging circuit and second input signals representing fixed pixel values from the imaging circuit at an input; determining whether the received signals are first input signals or second input signals; based on a determination that the received signals are first input signals, actuating multiple switches to a first configuration in response to a set of first control signals; propagating, via a change from a first state of a first component to a second state, a signal representing the first input signals to an amplifier input, wherein the output of the amplifier is a continuous-time amplified signal; placing the multiple switches in a second configuration in response to a set of second control signals, wherein output of the set of second control signals is based on the determination that the received signals are second input signals; holding the second input signals at the first component when the set of second control signals place the multiple switches in a second configuration.
