Abstract
A level-shifting circuit includes a first supply terminal configured to receive a first supply voltage, a second supply terminal configured to receive a second supply voltage different from the first supply voltage, an input terminal of the level-shifting circuit configured to receive a voltage having a first voltage level, and an output terminal of the level-shifting circuit. The level-shifting circuit can include a shifting circuit having electrical connections to the input terminal and the output terminal and configured to, in response to a first voltage at a first node, produce a second voltage at a second node. The level-shifting circuit can also include a feedback circuit and a clamping circuit configured to limit leakage current.
