ABSTRACT:
A level shift circuit with high switching speed and low power dissipation is described. The circuit includes two short channel transistors, two long channel transistors, and two switching transistors. Short channel transistors are arranged to receive a high input voltage presenting relatively low impedance and low capacitance. Long channel transistors are arranged to receive a first voltage from the short channel transistors and provide an output voltage and an inverted output voltage, which are also employed to control the short channel transistors. A first switching transistor of the switching circuit enables the short channel and the long channel circuits to provide the output voltage based on a low input voltage and a logic input voltage. A second switching transistor enables the same circuits to provide the inverted output voltage based on the logic input voltage.
