Abstract

This paper presents a new mutually coupled circuit (MCC) based on voltage differencing current conveyor (VDCC). The proposed MCC has been designed using the Gorski-Popiel technique. The proposed circuit consists of two VDCCs as active elements, three resistors, and two grounded capacitors as passive elements. The primary and secondary self-inductances and the mutual inductance can be controlled independently and can be adjusted electronically by the bias current of the VDCCs. There is only one matching condition for satisfying symmetrical coupling. Time and frequency-domain analyses have been performed with the LTspice program to verify the theoretical analyses. A double-tuned band-pass filter application is given to show the functionality of the proposed MCC.
