The present invention is a novel and improved method and apparatus of multiplying an analog signal by a pulse modulated signal. The apparatus includes a CMOS or equivalent gate. The pulse modulated signal is applied to the input of the gate. The analog control signal is applied to the power pin of the part. The output of the gate is the product of the two signals. The output may be lowpass filtered to obtain a resultant analog value. A scaling and offset circuit can be used to scale the output to comprise a zero pulse width modulation value wherein the value of the analog control signal has no affect on the resultant analog value.
