1. a level shifting circuit is used to produce its logic level and compares the output signal with magnitude of voltage inequality with the respective logic level of input signal, and described circuit comprises:

  • The switch current generator, its switching in response to input signal produces switch current, so that output signal is switched, andThe holding current generator is used to produce holding current, so that keep the logic level of output signal according to logical level of input signals,The holding current generator is configured to be independent of switch current and produces holding current.
