Abstract
A rectifier/multiplier/level shifter utilizing multiple capacitors which are switched from parallel to series or vice versa. An analog signal is communicated to a plurality of capacitors in parallel which are subsequently connected in series by selective switching. Depending upon the sign of the analog signal, taps are made on the capacitors so as to rectify the incoming analog signal. In a similar fashion a tap utilizes the serial multiplication of the capacitors so as to create a multiplier circuit. This particular architecture is particularly well suited for a metal-oxide-silicon (MOS) embodiment.
