Abstract
A voltage-to-time converter circuit receives a first voltage signal and produces a PWM-modulated signal having a duty-cycle proportional to the first voltage signal. A current integrator circuit receives the PWM-modulated signal from the voltage-to-time converter circuit block and produces an output signal by integrating a current signal from a current source over integration time intervals having a duration which is a function of the duty-cycle of the PWM-modulated signal. The current signal is proportional to a second voltage signal. The output signal is accordingly proportional to a product of the first voltage signal and the current signal, which is furthermore proportional to a product of the first voltage signal and the second voltage signal.
