Abstract
The present disclosure relates to a solid-state imaging apparatus, a method for driving the solid-state imaging apparatus, and electronic equipment for improving the determination speed of comparators and allowing the comparators to operate faster. A differential input circuit operates on a first power supply voltage and outputs a signal when a voltage of a pixel signal is higher than a voltage of a reference signal. A voltage conversion circuit converts the output signal from the differential input circuit into a signal corresponding to a second power supply voltage. A positive feedback circuit accelerates a transition rate at which a comparison result signal of a comparison in voltage between the pixel signal and the reference signal is inverted. Multiple time code transfer sections each include a shift register that transfer a time code. The present disclosure can be applied, for example, to an imaging apparatus including A/D converters disposed in pixels.
