ABSTRACT:
An integrated circuit voltage reference (V.sub.REF) for MOS circuit utilization is supplied by the weighted difference amplification (30) of the voltages (V.sub.1, V.sub.1 ') developed by a pair of separate similar networks (10, 10' or 100, 100') each of which comprises a base-emitter junction of a bipolar semiconductor transistor (T.sub.1) whose emitter is connected to a first clocked voltage source (C.sub.1, C.sub.2, M.sub.1, M.sub.2) in a feedback loop of a difference amplifier (A.sub.1) and whose collector is connected to receive output of a second clocked voltage source (C.sub.3, C.sub.4, M.sub.3, M.sub.4) and to deliver output to a first input terminal of the difference amplifier (A.sub.1). In a preferred embodiment, a second input terminal of the difference amplifier (A.sub.1) is supplied by the output voltage of an auxiliary voltage source (C.sub.5, C.sub.6, M.sub.6, M.sub.7, M.sub.8, M.sub.9) which is in another feedback loop of this amplifier (A.sub.1).
