Abstract :
A novel method for realising a mutually coupled circuit using operational transconductance amplifiers (OTAs) as active elements is proposed. The realised circuit is composed of eight OTAs and two grounded capacitors, and the values of a primary selfinductance, a secondary selfinductance and a mutual inductance can be independently tuned through the bias currents of the OTAs.
