Voltage level shifter and phase splitter |
摘要 |
A high speed voltage level shifter and phase splitter circuit is provided. The voltage level shifter and phase splitter circuit includes an input signal and a first input inverter stage that receives the input signal and provides an inverted delayed out of phase signal to the input signal. A buffer stage receives the input signal and provides a buffered delayed in phase signal to the input signal. A first constant current source is coupled between the first input inverter stage and the buffer stage. A first output inverter stage is coupled to the first constant current source and provides a voltage level shifted and out of phase signal to the input signal. A second constant current source is coupled between the first input inverter stage and the buffer stage having an opposite polarity as the first constant current source. A second output inverter stage is coupled to the second constant current source and providing a voltage level shifted and in phase signal to the input signal.
