Abstract

En un arreglo conocido de circuito se provee entre la salida del amplificador diferencial (Diff - Amp) y la entrada del regulador (R) un circuito de compensacion (KS) que en su curso de curva genera una senal de compensacion a la senal parasita con la misma amplitud y frecuencia (Phil) que la senal parasita pero desplazada 180¦ en fase de la cual se sustrae la senal diferencial (?Vs) y de esta manera la senal parasita se disminuye ampliamente.
