ABSTRACT:
A multiplication circuit for controlling an analog input voltage by the use of a switching signal created by a digital voltage so as to either generate an analog output or to cut-off the output. A digital input signal having a plural number of bits with given weights are introduced by use of capacitive coupling, and the resulting total becomes the multiplication result.
