Mutually coupled circuits based on modified voltage differencing transconductance amplifier with tuneable characteristics

Abstract

The paper presents a new mutually coupled circuit (MCC) based on a modified voltage differencing transconductance amplifier (MVDTA), designed using the modified Gorski-Popiel technique. The proposed synthetic transformer (ST) circuit uses two MVDTAs as active elements, and all passive elements are grounded-two capacitors and two resistors. Thanks to the newly established coupling method-connections, it is provided with independent electronic control of primary and secondary self-inductance, as well as mutual inductance, via bias voltages of MVDTAs. In addition, it is very easy to provide the conditions by which symmetrical couplings are achieved. Monte Carlo analysis is
