ABSTRACT:
An analog transversal filter includes a charge transfer delay line, including a plurality of cells for storing electrical charge, and a multiphase clock to transfer electrical charge from cell to cell through the delay line. A plurality of injection electrodes are connected to predetermined ones of the cells to sample an electrical signal, weight the signal sample a predetermined amount, and inject a charge packet representing the weighted signal sample into the cell. An output electrode collects and sums the charge packets transferred through the delay line. In another embodiment, the filter includes a plurality of charge transfer delay lines, with a plurality of cells for storing electrical charge in each delay line. A third embodiment includes a charge transfer delay line with a plurality of stages, each stage including a plurality of cells for storing electrical charge such that the cells of each stage are wider, in a direction transverse to the direction of charge transfer in the delay line, than the cells of preceding stages within the delay line. A plurality of end injection electrodes, each connected to one of the stages, and a plurality of side injection electrodes, each connected to a predetermined one of the cells, sample the signal, weight the signal sample a predetermined amount, and inject a charge packet representing the weighted signal sample into the stage or the cell, respectively.
