Applicant: Silicon Laboratories Inc.

Inventor： Nicholas Montgomery Atkinson ,  Praveen Kallam ,  Mohamed Mostafa Elsayed

IPC: H03K19/00 ,  H03K5/06 ,  H03K5/24

CPC classification number: H03K19/0016 ,  H03K5/06 ,  H03K5/2481

Abstract: In one embodiment, a voltage comparator circuit includes a first comparator circuit to compare a first voltage and a second voltage and a second comparator circuit to compare the first voltage and the second voltage. The voltage comparator circuit may include charge storage circuitry and positive feedback circuitry. Such circuitry may boost current within the first and second comparator circuits to enable the voltage comparator circuit to output a comparison decision within a delay threshold in response to input transitions within a slew rate threshold.
