Abstract
A high-speed regeneration comparator is disclosed in the present invention. The high-speed comparator is consisted of two capacitors and two inverters. A first terminal of a first capacitor is coupled with a reference voltage through a first switch and with an inputting voltage through a second switch. The inputting terminal of a first inverter is coupled with a second terminal of the first capacitor and the inputting terminal of the first inverter is coupled with the outputting terminal of the first inverter through a third switch for feedback signals from the outputting terminal of the first inverter to the inputting terminal of the first inverter. A first terminal of a second capacitor is coupled with the outputting terminal of the first inverter. An inputting terminal of the second inverter is coupled with a second terminal of the second capacitor and the outputting terminal of the second inverter is coupled with the inputting terminal of the first inverter through a fourth switch and a fifth switch is coupled with the second inverter in parallel.
