Abstract :
A simple rearrangement of the usual waveforms and voltage levels on the input terminals of a charge-coupled device can be used to integrate the input signal during the intersample interval. The method automatically provides a lowpass filter characteristic matched to the sampling time and tends to suppress high-frequency components and hence reduces aliasing problems. Adequate linearity and dynamic range are demonstrated.
