Abstract:
1. A voltage level shifter apparatus for receiving an input data signal and outputting an output data signal with different levels accordingly, comprising: a first dynamic-bias generator for outputting a first bias signal, herein the first dynamic-bias generator further dynamically determines a level of the first bias signal in accordance with an in-phase signal of the input data signal and an out-of-phase signal of the input data signal, including: a second dynamic-bias generator for outputting a second bias signal, wherein the second dynamic-bias generator further dynamically determines a level of the second bias signal in accordance with the in-phase signal of the input data signal and the out-of-phase signal of the input data signal; and a level supply circuit coupled to the first dynamic-bias generator and the second dynamic-bias generator, for receiving the input data signal and generating the output data signal in accordance with the first bias signal and the second bias signal.
