Abstract :
A circuit is presented for the simulation of electronically tunable impedance. It employs two operational amplifiers, an MOS resistive circuit (MRC) and passive components. It enables the wide range linear tuning of impedance values through the voltage control of the MRC and is therefore well suited for the design of programmable filters and oscillators
