Abstract
Describes the design and performance of a 64-stage, electronically programmable, binary-analog transversal input filter (PTIF). The monolithic filter consists of an array of two-phase buried-channel CCDs with surface channel inputs, operated in a single-ended configuration and driven with a single clock. Digital NMOS support circuitry permits programming of bipolar weighting coefficients while maintaining code independent offset. The device has been operated as a pseudorandom noise sequence matched filter with a dynamic range of 55 dB at 8 MHz and a near theoretical processing gain of 18 dB. Correlation has been demonstrated at 20 MHz.Keywords
