Voltage level shifter

Abstract

A voltage level shifter is provided. The voltage level shifter includes a voltage level shift circuit and a boost circuit. The voltage level shift circuit operates between a first voltage and a second voltage. The voltage level shift circuit includes a pair of cross-coupled transistors and a pair of differential transistors. The pair of differential transistors is coupled to the pair of cross-coupled transistors and receives a pair of input signals. The boost circuit is coupled to the voltage level shift circuit. The boost circuit executes a pre-charging operation on boost input terminals of the pair of cross-coupled transistors, generates a voltage pulse based on a charge pump operation according to a control pulse signal, and provides the voltage pulse to the boost input terminals. The control pulse signal is generated corresponding to a transient edge of the pair of input signals.
