Abstract
A voltage level shifter to provide an output logic signal in response to an input logic signal, where the input logic signal is in a first voltage domain and the output logic signal is in a second voltage domain. In one embodiment, a voltage boost module provides a boosted voltage in response to the input logic signal going HIGH, where the boosted voltage is sufficient to turn OFF a pull-up transistor operating in the second voltage domain. Contention among pull-down and pull-up transistors may be avoided.
