Patent ID: 10284187

Abstract:
A comparator includes a differential input pair of transistors, a pair of cross coupled n-channel metal-oxide-semiconductor field-effect (NMOS) transistors, a pair of p-channel metal-oxide semiconductor field-effect (PMOS) transistors, a first inverter, and a second inverter. The differential input pair of transistors includes a first input transistor and a second input transistor. The pair of cross coupled NMOS transistors includes a first NMOS transistor and a second NMOS transistor. The pair of PMOS transistors includes a first PMOS transistor and a second PMOS transistor. The pair of PMOS transistors are coupled to the pair of cross coupled NMOS transistors. The first inverter is coupled in series with the first PMOS transistor. The second inverter is coupled in series with the second PMOS transistor.
