A prototype of a CCD programmable transversal filter is described. The tap weights have been implemented by on-chip voltage-controlled variable MOS 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 nonlinear distortion below -45 dB.
