Abstract
A CCD imaging array includes one or more shift registers. By injecting a charge packet at one end of the shift register, at times related to the start of line read out, then the charge packet reaches the other end of the shift register at the end of the line period. Thus the shift register can be used to generate line synchronization signals. The technique can also be applied for more complex waveform generation and for field generation.
