ABSTRACT:
In a charge transfer device electrode operating voltage is applied through a high-gain differential amplifier having an inverting and a non-inverting input terminal with capacitive feedback from the output terminal to the inverting terminal. The inverting terminal is connected to the charge transfer device electrode. The non-inverting terminal is connected to a source of operating voltage. During the transfer of charge the voltage on the electrode is maintained substantially constant and a voltage change is produced at the output of the amplifier which is approximately equal to the induced charge divided by the feedback capacitance.
