ABSTRACT:
A high voltage input receiver using low voltage transistors is disclosed. In one embodiment, an input receiver circuit includes a comparator circuit and an inverter circuit. The comparator circuit includes a differential input module for generating a control signal by comparing an external voltage and a reference voltage, and a decision module for generating an inverter input signal based on the control signal. In addition, the reference voltage is used to set dc trip point of the input receiver. Moreover, the input receiver includes one or more stress protection modules to protect key components of the input receiver from exceeding their reliability limits.
