Abstract
Abstract A charge coupled device has a circuit for handling a fundamental clock signal to produce a particular driving signal in the device, and independent power supply lines and/or ground lines. One power supply line and/or one ground line is exclusive for the circuit for handling the fundamental clock signal. The interference by the fundamental clock signal is prevented by the separation of power supply line and/or ground line.
