Notes on Voltage-Tunable Nonlinear Resistance-Capacitance Networks

Nonlinear resistances possess dynamic resistances that can be electrically varied over a range of many orders of magnitude. In this respect, they are far more nonlinear than contemporary nonlinear reactances. Some general criteria for obtaining maximum voltage tunability are discussed and several networks possessing zero-phase frequencies are presented for possible use in wide-range voltage-tunable resistor-capacitor (RC) networks.
