Abstract
An analog multiplier feedforward technique for use in the feedback loop of a switching regulator circuit is provided. The analog multiplier eliminates the necessity for the output of the error amplifier to the regulator circuit to change voltage when regulator input voltage changes, and makes "loop" gain independent of input voltage.
