Signal synthesizer apparatus

摘要

A signal synthesizer apparatus having a parameter dependent multiplier which includes charge-coupled devices. The multiplier has a gating input to store a charge corresponding to an input signal applied thereto; a first set of transmission gates for selectively transferring portions of the stored input charge, the selectivity of the transmission gates being dependent on a prescribed parameter; a plurality of intermediate electrodes for storing the charges transferred by the transmission gates; a second set of transmission gates for transferring the charges stored by the intermediate electrodes; and an output electrode for combining all of the charges transferred from the intermediate electrodes by the second set of transmission gates. The signal output by the multiplier corresponds to the magnitude of the combined charges of the output electrode.
