ABSTRACT:
An input scheme suitable for low-level input signals, e.g., from an IR detector array, wherein the input signals are transferred over respective channels to parallel inputs of a charge transfer device shift register, under control of IGFET switching transistor circuits in each channel. Corresponding IGFETS in the channels are operated by common gate voltages. Introduction of noise due to variation of the gate threshold voltages between IGFETS in the transfer circuits is obviated by using the same IGFET in each channel to reset the potential at the input node of that channel as well as to transfer the input signals over that channel to the shift register.
