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.

Abstract: An example sample-and-hold circuit includes a first and second input resistors, each having first and second terminals; first and second transistors coupled in series between the second terminals of the first and second input resistors; and third and fourth input resistors, each having first and second terminals; and third and fourth transistors coupled in series between the second terminals of the third and fourth input resistors. The control terminals of the first and third transistors are coupled together, and the control terminals of the second and fourth transistors are coupled together.
