摘要： An output signal processing circuit for a CCD register, for example a horizontal output register of a CCD imager is provided. The CCD register includes an output precharge circuit with a capacitance, the voltage across the capacitance is supplied to an output terminal of the CCD register and has first, second and third durations repeatedly. The first duration is a precharge duration, the second duration is a reference duration and the third duraiton is a signal duration. The output signal processing circuit includes a clamp circuit(3) for clamping the output signal at the output terminal of the CCD in such a manner that the voltage of the reference duration becomes a stable clamp voltage, clip circuit (8) for clipping the output signal of the clamp circuit such that the voltage of the precharge duration is clipped to a clip level, and a low-pass filter (11)suppliedwith the output of the clip circuit(8) for generating the transferred signal.
