ABSTRACT:
The CMOS sensor circuit comprises a photodiode, a reset transistor resetting the photodiode to an initial voltage, and a voltage control circuit controlling a gate potential of the reset transistor to a potential other than power source potentials. The voltage control circuit consists of an inverter circuit driving a gate of the reset transistor. The inverter circuit includes a P-channel MOS transistor, an N-channel MOS transistor, and a transistor inserted between a drain of the P-channel MOS transistor and a drain of the N-channel MOS transistor so as to control a blooming.
