Özet

This paper presents a novel mutually coupled circuit (MCC) based on the current conveyor transconductance amplifier (CCTA). The proposed MCC includes two CCTAs, three resistors, and two grounded capacitors. The mutual and the self-inductances can be controlled independently and electronically. There is a single matching condition for satisfying symmetrical coupling. The simulation results have been obtained with the LTspice program using 0.13 mu m IBM CMOS technology parameters. As an application example, a double-tuned band-pass (DTBP) filter is provided to demonstrate the workability of the proposed MCC. An experimental study is conducted to confirm the time-domain and frequency domain performance of the DTBP filter by utilizing commercially available integrated circuits (ICs).
