Abstract:
1. A horizontal charge coupled device (CCD) driving circuit of a solid-state image-sensing device, the horizontal CCD driving circuit comprising: an inverter for inverting a clock signal and outputting a first horizontal driving signal; a buffer circuit for buffering the clock signal and outputting a second horizontal driving signal; a first output switch for selectively outputting or not outputting the first horizontal driving signal in response to a logic state of a first control signal; a second output switch for selectively outputting or not outputting the second horizontal driving signal in response to the logic state of the first control signal; and an equipotential switch for selectively short-circuiting or disconnecting output terminals of the first and second horizontal driving signals of the first and second output switches in response to a logic state of a second control signal, wherein the logic state of the second control signal changes at a different time than the logic state of the first control signal, wherein the first control signal changes from a second logic state to a first logic state and remains in the first logic state for a predetermined time after rising and falling of the clock signal.
