Abstract
In this paper a bilateral resistive circuit is designed and presented with is work as a positive and negative electronically tunable resistor and has zero DC offset. The proposed topology is designed by paralleling two electronically tunable resistors to obtain lower resistive values and decreasing nonlinearity percent. The proposed topology is low voltage and low power and with proper transcurrent circuit, its current–voltage characteristics can be linear, expansive (square) and compressive (square root). Its supply voltages are ±1 V and its dynamic range is ±1 V too. The designed circuit is simulated in an industrial 65 nm CMOS process. The linear version is tunable over the wide resistance range of 7 kΩ–37 GΩ.
