Abstract
A multiplier circuit to multiply a first signal with a second signal includes an analog-to-digital converter that has a first input and a second input. The first input is to receive the first signal. The multiplier circuit also has an inverting circuit having an input to receive the second signal, and an output connected to the second input of the analog-to-digital converter. An output value produced by a combination of the analog-to-digital converter and the inverting circuit is approximately a multiplication of the first signal and the second signal.
