Abstract
In one embodiment, a voltage level shifter includes a first NOR gate having a first input configured to receive a first input signal in a first power domain, a second input configured to receive an enable signal in a second power domain, a third input, and an output. The voltage level shifter also includes a second NOR gate having a first input configured to receive a second input signal in the first power domain, a second input configured to receive the enable signal in the second power domain, a third input coupled to the output of the first NOR gate, and an output coupled to the third input of the first NOR gate. The first and second NOR gates are powered by a supply voltage of the second power domain.
