Input buffer regenerative latch

摘要

An input buffer for converting ECL signals to CMOS signals in a BiCMOS chip. The buffer has an emitter follower circuit for receiving the ECL input signal and is coupled to a static amplifier. The output of the static amplifier is forwarded to a differential amplifier which is activated by a clock signal whenever an ECL high level input is applied to the buffer circuit. The differential voltage output from the differential amplifier represents the CMOS level signal.
