The remote variable resistor functions as a voltage-controlled resistor whose resistance changes based on an applied voltage.

In this paper, a new coupling circuit is presented. This circuit uses a new method of subthreshold region biasing to decrease the value of coupling capacitor. In proposed circuit the Coupling ...
