Abstract
A multiplication circuit has two capacitive couplings connected first and second inverting amplifiers, respectively. Two steps of multiplication are performed by this circuit. Input is multiplied by a multiplier of a product of multipliers of the successive multiplication circuits, so the total multiplier can be rather large with similar capacitances to that of the conventional circuit.
