ABSTRACT:
A multiplexer circuit is disclosed, for use with such signal sources as focal plane detector arrays, which contains a large number of parallel branches, each of which includes a transconductance MOSFET amplifier and a MOSFET switch of opposite channel polarity from the amplifier. The amplifier in each branch receives high impedance voltage signals originating from its individual detector and converts them with high power gain into current signals which feed into the common output line whenever the switch in the same branch is turned on. The multiplexer branches, together with the multiplexer control logic, and other electronic devices, are all included on a signal IC chip which provides CMOS logic.
