摘要： For raising low voltage levels of a voltage range without over-broadening the voltage range, a first stage voltage level shifting circuit, which is capable of raising an upper bound of its input voltage range, is coupled to a second voltage level shifting circuit, which is capable of raising both an upper bound and a lower bound of its input voltage range. Therefore, a two-stage voltage level shifting module, which is generated by coupling the first voltage level shifting circuit to the second voltage level shifting circuit, is capable of providing appropriate voltages for external I/O devices having different biasing voltage ranges, where an upper bound and a lower bound of each of the provided biasing voltage ranges precisely indicates a digital logic 0 or a digital logic 1 indicated by a digital signal.
