Abstract
A BIMOS circuit is provided wherein an output terminal is coupled between upper and lower NPN push-pull transistors for providing high current drive capability along with no d.c. power dissipation. A first MOS transistor circuit is coupled to the lower transistor for biasing the lower transistor. A second MOS transistor circuit is coupled between an input terminal and both the upper transistor and the first MOS transistor circuit for providing a high impedance at the input and for biasing both the upper transistor and the first MOS transistor circuit, wherein the first circuit is biased with a larger voltage than the upper transistor for improving the switching speed of the output signal.
