Abstract
A voltage level shifter is provided. The voltage level shifter includes a main level shifter, a first bias level shifter and a second bias level shifter. The main level shifter includes a first N-type transistor and a second N-type transistor cross-coupled to each other, a third N-type transistor and a fourth N-type transistor controlled by a first bias voltage, a fifth N-type transistor and a sixth N-type transistor respectively controlled by a second bias voltage and a third bias voltage, and a first P-type transistor and a second P-type transistor configured to respectively receive an input signal and an inverted input signal which have opposite voltage values. The first bias level shifter generates the first bias voltage according to an enable signal. The second bias level shifter generates the second bias voltage and the third bias voltage according to the first bias voltage and the input signal.
