Abstract

An integrated circuit includes an input pad and a Schmitt trigger coupled to the input pad. The Schmitt trigger includes a main PMOS branch that charges an intermediate node of the Schmitt trigger responsive to voltage transitions at the input node. The Schmitt trigger includes a charging assistance circuit that helps to rapidly charge the intermediate node of the Schmitt trigger. The charging assistance circuit includes a parallel PMOS branch in parallel with the main PMOS branch.
