Reflected signals have always been considered a curse by circuit designers, wasting energy, reducing gain and adversely affect-ing system performance. This article describes a new technique that uses this normally trouble-some reflected signal to cancel output distor-tion, significantly increase linearity, and dou-ble the usable output power of single stage amplifiers.
