Abstract
A differential input buffer operable at power supply voltages below 3.0 V comprises first and second field effect transistors connected between a power supply and a current source as a differential pair in receiving input and input bar signals. Using enhancement mode field effect transistors and heterojunction bipolar transistors for a current source, a power supply voltage Vcc as low as 2 V is possible for circuit operation.
