A multiplier circuit can be fabricated within an integrated circuit and can draw a product output node to a voltage proportional to a product of first and second binary numbers received at two sets of inputs. The multiplier circuit includes a set of scaled capacitors, each capacitor of the set connected to an output of a multiplexor and to a local product output node. Each multiplexor is connected to the output of a multiplexor configured to generate an analog voltage in proportion to the value of the first binary number. Each scaled capacitor has a capacitance proportional to a significance of a respective bit of the second binary number. The multiplier circuit includes a reference capacitor connected to ground and the product output node, and a reset circuit configured to draw, in response to a RESET signal, the product output node to ground.
