摘要： A charge detection circuit is capable of converting electrostatic charge quantities on a solid-state imaging chip into voltage signals of negative polarity. The voltage signals of the negative polarity are suppled to a DC-coupled polarity inversion circuit which inverts the polarity of the signals and amplifies the signals. In consequence, the generation of heat in the transistor of the outpout stage is reduced so as to suppress undesirable temperature rise of the solid-state imaging chip.
