Abstract
A solid-state imaging deviceincludes photodiodes PDto PD, charge-voltage converting circuitsto, pre-holding circuitsto, a transimpedance amplifier, a peak holding circuit, and a post-holding circuit. The charge-voltage converting circuitinputs charges generated at the photodiode PDand outputs a voltage value corresponding to the input charge quantity. The pre-holding circuitholds the output voltage value from the charge-voltage converting circuitand outputs the output voltage value as a current. The transimpedance amplifierinputs voltage values successively output form the pre-holding circuitstoas currents and outputs voltage values converted based on a transimpedance from the currents flowing in accordance with change quantities to the input voltage values from a reference voltage value. The peak holding circuitholds and outputs a peak hold voltage of the output voltage values from the transimpedance amplifier
