In this paper, it presents that novel Voltage-Controlled Nagativd-Resistance Circuit which composed by two Current mirror, and this presumes, interprets Co-operation of Circuit. Indeed, its to increase the peak Voltage Vp, whch is done by inserting a Zener Diode in series with R-experimental results and to presents the various Negative-Resistance Characteristic Confirmed with Conincided Substantially presumed realization of Circuit corperation and Calculated was Checked through experiments.
