Abstract:
1. A solid-state imaging apparatus comprising: a column circuit that includes: wherein, at a state of supplying a signal from the output node of the one of the common output units to the input node of the one of the common output units through the feedback path, a corresponding selecting unit is shifted to a conducting state so that a corresponding signal holding unit performs a clamping operation to clamp a signal outputted from a corresponding pixel, and wherein the clamping operation is performed such that a time changing rate of an amplitude of a drive pulse supplied to the corresponding selecting unit for shifting from a non-conducting state to the conducting state is greater than a time changing rate of the amplitude of the drive pulse supplied to the corresponding selecting unit for shifting from the conducting state to the non-conducting state; a driving unit for supplying the drive pulse to the selecting units, a monitoring unit for monitoring the time changing rate of the amplitude of the drive pulse, wherein the monitoring unit feeds back a monitoring result to the constant current source to adjust a current value of the constant current source so as to maintain constant the time changing rate of the amplitude of the drive pulse.
