Differential to single-ended converter utilizing inverted transistors

摘要

A differential to single-ended converter circuit is disclosed which utilizes integrated injection logic device geometrics to significantly reduce the area required to fabricate the converter within an integrated circuit. Inverted transistor operation and multiple collector output terminals allow the converter circuit to directly drive integrated injection logic circuitry which may be fabricated within the same integrated circuit chip. When used in conjunction with a voltage comparator circuit, the differential to single-ended converter circuit maintains the offset associated with the comparator circuit at a minimum despite variations in operating temperature and variations in integrated circuit processing.
