ABSTRACT:
In a GaAs IC using an E/R type DCFL circuit or E/D type DCFL circuit, a Schottky barrier diode is connected between the positive polarity power source of the DCFL circuit and a load element. A deterioration of switching speed is prevented even in case of using a power source voltage of 2 V in the GaAs IC. Addition of the Schottky barrier diode in a super buffer circuit to prevent a slow increase in output voltage in the circuit is also disclosed.
