Abstract :
A negative-resistance, fully floating voltage-controlled resistor with wide input voltage range, and negative slope voltage-to-current characteristics passing through the origin with high linearity is presented. It is based on the bisection of the input voltage. Negative resistances have been achieved by using a voltage-controlled current source and one junction field effect transistor operating in nonsaturated region. Simulation results obtained for the input voltage ranges from -1 V to 1 V, from -3 V to 3 V, and from -5 V to 5 V show high linearity and frequency bandwidth between 1 MHz and 10 MHz
