Abstract
In one general aspect, a level-shifting circuit includes a first supply terminal configured to receive a first supply voltage, and a second supply terminal configured to receive a second supply voltage different from the first supply voltage. The level-shifting circuit includes a shifting circuit having electrical connections to an input terminal and an output terminal and configured to, in response to a first voltage at a first node, produce a second voltage at a second node. The shifting circuit is used to shift a first voltage level to a second voltage level. The level-shifting circuit includes a clamping circuit having an electrical connection to the first node where the clamping circuit is configured to limit current at the first node from flowing to a ground.
