Abstract
A general purpose charge mode, analog operation circuit provides adder, multiplier, divider (D/A converter) and other functions using a single hardware configuration to be used in different modes. A two-dimensional lattice circuit including electrical charge transfer devices, each driven by charge transfer electrodes, all or a portion of which having structures allowing independent control, and a plurality of the electrical charge transfer devices adjacent to each other in the circuit are controlled successively with respect to the analog circuit charge signals to provide operation functions such as addition, multiplication, division, and sign inversion.
