Abstract
A voltage level shifter is provided for receiving an input signal from an input voltage domain and converting said signal to a shifted signal in a shifted voltage domain. The voltage level shifter has an input, switching circuitry, a pass transistor and an output. The switching circuitry is configured to isolate an output of said pass transistor from said supply voltage rail when said input voltage domain corresponds to a logical zero.
