Abstract
Provided herein is a voltage level shifter, an apparatus including a voltage level shifter and a method of converting voltages between input and output power domains. In one embodiment, the voltage level shifter includes: (1) an input circuit configured to receive a data signal from an input power domain and a power down signal from a output power domain and (2) a transition circuit coupled to the input circuit and configured to receive the data signal and an inverted signal of the power down signal, wherein the input circuit and the transition circuit are both configured to connect to a supply voltage of the output power domain as a power source.
