Gated transmission circuit (on-chip).

摘要

A gated binary signal transmission circuit in a field effect semiconductor chip comprises a single signal-pass transistor (20A, B) connected between a bit signal input (28A, B) to one of its electrodes (24A, B) and a bit signal output (12A, B) from another of its electrodes (26A, B). Its control electrode (22A, B) is connected for temporary energisations by switching circuitry (32,34) operative only at prescribed intervals, the single signal-pass transistor (20A, B) being operative to pass signals between such energisations of its control electrode (22A, B). Conduction of the single signal-pass transistor between energisations will persist, though with some decay, due to inherent capacitance and the control electrode being left "floating" between energisations.
