Glitch-free wide supply range transceiver for integrated circuits

Abstract:

An example receiver includes: a pad splitter circuit coupled to a pad, the pad splitter circuit configured to generate a first logic signal and a second logic signal; a wide-range receiver coupled to the pad splitter circuit to receive the first and second logic signals, the wide-range receiver comprising a combination of a first Schmitt trigger receiver and a second Schmitt trigger receiver; a control circuit coupled to the pad splitter circuit and the wide-range receiver; and a bias generator circuit coupled to the pad splitter circuit and the wide-range receiver.
