Abstract:
A photoelectric conversion apparatus comprises: a first current amplifier for amplifying a current input through a first current input terminal; a first initializing unit for initializing a voltage of the first current input terminal; a first detector for detecting the voltage of the first current input terminal; a first feedback unit for feeding back the voltage to the first current amplifier; and a correction unit including a second current amplifier for amplifying a current input through a second current input terminal; a second initializing unit for initializing a voltage input through the second current input terminal; a second detector for detecting the voltage of the second current input terminal; a second feedback unit for feeding back the voltage detected by the second detector to the second current amplifier; and an arithmetic operation unit for correcting the current amplified by the first current amplifier.
