Abstract
Some general aspects of the invention relate to a circuit and to a method for analog computation, for example, using switched capacitor integrated circuits. In some examples, a circuit includes a first group of capacitors and a second group of capacitors that may store charges during circuit operation. The first and/or the second group of capacitors may include multiple disjoint subsets of capacitors. An input circuit is provided for receiving a set of input signals and for inducing a charge on each of some or all capacitors in the first group of capacitors according to a corresponding input signal. Switches, for example, transistors controlled by a sequence of clock signals, are used to couple different sets of capacitors. Different configurations of the switches are used to form different sets of the capacitors among which charge can redistribute.
