ABSTRACT:
A signal sampling circuit comprising a signal inverting amplifier with a gain greater than unity, an input clamp network including a feedback switch, and an output sampling network including a charge storage device and a sampling switch is disclosed. The amplifier input to which signals to be sampled are applied is clamped to the amplifier output potential via the feedback switch during non-sampling, clamping intervals. During subsequent sampling intervals, the feedback switch is disabled and the sampling switch is enabled to couple the amplifier output to the storage device, so that the storage device develops a voltage sample of amplifier output signals referenced to the clamping potential.
