Document Type and Number:
Japanese Patent JP6562243
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an imaging apparatus capable of reducing influences of noises.SOLUTION: An imaging apparatus 100 includes: a unit pixel cell 10A which has a photoelectric conversion part and signal detection circuit that detects a signal generated by the photoelectric conversion part; and a voltage supply circuit 50A that supplies a gradient voltage to the unit pixel cell. The voltage supply circuit includes: a gradient voltage generation circuit 52; a first amplifier 54; a capacitive element 56 which is connected to the gradient voltage generation circuit and the first amplifier therebetween; and a first feedback circuit for performing negative feedback of the output from the first amplifier. The first feedback circuit includes a switch 60 which selectively forms a feedback loop.SELECTED DRAWING: Figure 1
