Abstract
The present disclosure provides a high-speed regenerative comparator circuit, including: a signal input stage connected with an input terminal for differential signal input; a latch for caching and serving as a differential signal output terminal; a current source connected with the signal input stage for providing a power supply voltage; a fast path connected with the output terminal and used for increasing a voltage difference of the output terminal and turning on a positive feedback network of the latch; and a reset switch, including a first reset switch and a second reset switch. In the high-speed regenerative comparator circuit of the present disclosure, the transmission delay of the regenerative comparator circuit can be greatly reduced; and in a latch phase, a bias voltage is disconnected by means of timing control, and thus the power consumption of a comparator can be reduced. The present disclosure has simple circuit and high reliability.
