ABSTRACT:
A multiplex system wherein each of the multiplex circuits includes a hold switch and hold capacitor, a standard class A differential amplifier with constant feeding current source, a multiplex switch to selectively isolate each multiplex circuit from the common multiplex line and a second current source supplying much larger current than the constant feeding current source selectively couplable in parallel with the constant feeding current source to the differential amplifier during periods when the differential amplifier is coupled to the common multiplex line.
