ABSTRACT:
A voltage level shifter apparatus is provided. The voltage level shifter apparatus includes a first dynamic-bias generator, a second dynamic-bias generator, and a level supply circuit. The first dynamic-bias generator dynamically outputs a first bias signal, wherein the level of the first bias signal is determined in accordance with the received input data signal. The second dynamic-bias generator outputs a second bias signal, wherein the level of the second bias signal is determined in accordance with the received input data signal. Besides receiving the input data signal, the level supply circuit is further coupled to the first dynamic-bias generator and the second dynamic-bias generator for receiving the first bias signal and the second bias signal, and generating the output data signal in accordance with the input data signal, the first bias signal, and the second bias signal.
