ABSTRACT:
A high-voltage gain, high-current gain comparator circuit including a pair of input transistors, a constant current source, an unbalanced pair of multiple emitter active load transistors and a signal amplifier with emitter feedback to one of the active load transistors for achieving input signal hysteresis characteristics. The circuit has differential inputs, a single-ended output, inherent noise immunity and is particularly well suited for fabrication as an integrated circuit in a chip of semiconductor material.
