Abstract: Two matched lateral PNP current sources supplying operating currents to a monolithic integrated operational amplifier circuit each are comprised of transistors with segmented collector rings. The collector segments are interconnected with the collector conductors by fusible metal links which may be burned out or melted by supplying a pulse of high current through the fusible links. By selectively melting these links, the relative currents supplied by the two current sources may be adjusted during the measuring and probing of the integrated circuit chip prior to its packaging.

Abstract: A differential input stage for an integrated circuit operational amplifier, having low transconductance, yet having high frequency response. The low transconductance of the differential input stage is achieved without sacrificing frequency response by using multiple collector lateral PNP transistors, whereby only a fraction of the total PNP transistor current flows in the collector circuit and contributes to the transconductance of the differential amplifier stage.
