Abstract :
A prototype of a CCD programmable transversal filter is described. The tap weights have been implemented by on chip voltage controlled variable capacitors. The summation of the weighted tap signals uses a charge sensing technique. The performance of the filter has been demonstrated by suitable measurements, indicating a non-linear distortion below -45 dB.
