PASSING HIGH VOLTAGE INPUTS USING A CONTROLLED FLOATING PASS GATE

摘要

An input receiver includes a first pass transistor coupled between an input pad and an internal receiver node. The first pass transistor includes a controlled floating gate capacitively coupled to the input pad. A source follower transistor couples between the internal receiver node and a power supply. A gate for the source follower transistor couples to the input pad.

1. A circuit, comprising:
a non-native first pass transistor coupled between an input pad and an input receiver node, wherein the non-native first pass transistor includes a floating gate coupled to a power supply through a pair of diodes; and a source follower transistor having its gate coupled to the input pad, a first drain/source terminal coupled to the input receiver node, and a second drain/source terminal coupled to the power supply.
