Claims

[Scope of utility model registration request]

a first pulse generator that outputs a first clock pulse with a predetermined frequency; a second pulse generator that outputs a second clock pulse with a frequency different from the first clock pulse; The first charge transfer element is driven by the second clock pulse, and the second charge transfer element is also driven by the first and second clock pulses, and the signal line is switched at regular intervals. The first clock pulse is supplied to the first charge transfer element, the second clock pulse is supplied to the second charge transfer element, and the output signal of the second charge transfer element is self-feedback. the second clock pulse is supplied to the first charge transfer element, the first clock pulse is supplied to the second charge transfer element, and the second clock pulse is supplied to the second charge transfer element, and a control circuit that switches between a state in which the output signal of the first charge transfer device is self-feedback and outputted through the output terminal at each of the fixed periods; A frequency characterized in that one of the charge transfer elements outputs an output signal while performing self-feedback in synchronization with the second clock pulse, and the output signal is read into the other charge transfer element in synchronization with the first clock pulse.
