Abstract:
1. An apparatus comprising: a plurality of circuits each to couple to a different respective column of a pixel array, the plurality of circuits each including: control logic coupled to send first control signals and second control signals to each of the plurality of circuits, wherein for each of the plurality of circuits, the first control signals to select a respective first combination of the plurality of legs of the circuit to set the first configuration of the circuit, and the second control signals to select a respective second combination of the plurality of legs of the circuit to set the second configuration of the circuit, wherein the respective first combination is different from the respective second combination, wherein for each of the plurality of circuits, the control logic to select the respective first combination from a plurality of configurations in response to a signal indicating a reference loop gain, the plurality of configurations including configurations which each correspond to a respective loop gain substantially equal to the reference loop gain; and readout registers each coupled to a different respective one of the plurality of circuits, the readout registers arranged in a sequence, the control logic to successively shift the first control signals through the sequence and to successively shift the second control signals through the sequence.
