Abstract

A charge coupled device in which a row of electrodes is deposited over an insulating layer on a substrate has clocking pulses applied to some electrodes for clocking charge packets from source to drain gates and a steady or long pulses applied to other, tapping, electrodes. Amplifying circuitry connected to each tapping electrodes non-destructively measures the change in capacitance under the tapping electrode as a charge packet passes under it.
