  • Patent number: 5699007
    Abstract: A high-speed solid state buffer circuit and method for producing the same. A buffer circuit accepts logic input signals and transforms the signals to an output signal which can drive a heavy load. By using an output stage pull-up device that includes a parallel combination of an enhancement mode FET and a depletion mode FET, a solid-state buffer circuit with increased speed and output voltage swing is achieved. Most conveniently, the buffer takes the form of a logic inverter. However, the buffer can also be used to form a multiple input NOR gate. The circuit is most suitable for realization in GaAs technology.
