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 includes a first boost input terminal, a second boost input terminal, a first reference input terminal and a second reference input terminal. The voltage level shift circuit operates between a first voltage and a second voltage. The boost circuit is coupled to the voltage level shift circuit. The boost circuit is configured to pre-charge the first boost input terminal and the second boost input terminal to a third voltage value, and to boost the third voltage value to a fourth voltage value according to pair of differential signals provided to the first reference input terminal and the second reference input terminal.
