Abstract
A low-power level-shift circuit for data-dependent signals includes a buffer circuit, a coupling capacitor, and a biasing circuit. The buffer circuit is biased by a low-voltage domain voltage supply and configured to receive a data-dependent signal. The coupling capacitor is coupled, at a first node, to an output node of the buffer circuit. The biasing circuit is coupled to a second node of the coupling capacitor and a switch. The level-shift circuit can translate a voltage level of the received data-dependent signal to a high-voltage domain that is suitable for proper operation of the switch.
