“…A number of circuits have been published to simulate a MCC in the literature using operational amplifiers (Op-amps) [1][2][3], operational transconductance amplifiers (OTAs) [4][5][6], bipolar junction transistors (BJTs) [7,8], second-generation current conveyors (CCIIs) [9][10][11][12], current backward transconductance amplifiers (CBTAs) [13,14], current feedback operational amplifiers (CFOAs) [15], current conveyor transconductance amplifiers (CCTAs) [16,17], and voltage differencing current conveyors (VDCCs) [18]. Op-amp based realizations have some problems, such as constant gain-bandwidth product and low slew rate.…”

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 μm 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).

“…They can also be used for analog filters, particularly for replacing the magnetic transformer in staggertuned filters. Therefore, a variety of operational amplifier (Op-amp) based RC-active networks have been reported for the design of mutually coupled circuits [2,7,23]. However, new analog integrated circuit applications have emerged and the performance requirements for analog circuits have changed.…”

“…Several studies are proposed in the literature for simulating a mutually coupled circuit using operational amplifiers [2,7,23], bipolar junction transistors [8,21], second-generation current conveyors (CCII) [1,9,28], and the operational transconductance amplifier (OTA) [8,10]. However, current conveyor and current-conveyorbased active component realizations are more attractive due to the already mentioned properties, namely, higher signal bandwidth, greater linearity, wider dynamic range, simple circuitry, and low power consumption [24].…”

A novel circuit for the realization of the mutually coupled circuit using three current-controlled current backward transconductance amplifiers (CC-CBTAs) as active components is proposed. The active mutually coupled circuit structures are also called the synthetic transformers. The circuit is derived by using three floating simulated inductors that are connected as the T-type transformer model. The circuit has the following attractive advantages: (i) The values of a primary self-inductance, a secondary self-inductance and a mutual inductance can be independently tuned by the transconductance gain of the CC-CBTAs; (ii) The circuit uses three grounded capacitors that are suitable from the point of integrated circuit implementation; (iii) It uses only three active components; (iv) It has a good sensitivity performance with respect to the tracking errors; (v) Both positive and negative couplings are achieved and the coupling coefficient is not limited by 1 in magnitude; (vi) Symmetrical coupling is achieved without necessitating any matching condition; (vii) The proposed circuit has a floating structure.

“…A mutually coupled circuit comprises a primary self-inductance L 1 , a secondary self-inductance L 2 and a mutual inductance M. A literature survey reveals that several approaches have been reported for simulating a mutually coupled circuit using operational amplifiers (Atiya 1978, Soderstrand 1978, Higashimura and Fukui 1985, bipolar junction transistors (Higashimura andFukui 1991, Shigehiro et al 1991), second-generation current conveyors (CCIIs) (Higashimura 1991, Higashimura andFukui 1991a) and the operational transconductance amplifier (OTA) (Higashimura and Fukui 1991a,b). Of these, the CCII-based realizations are more attractive.…”

A new CCII-based circuit for the simulation of mutually coupled circuits is presented. The circuit uses six commercially available plus-type secondgeneration current conveyors (CCIIþs), six resistors and two grounded capacitors. The primary self-inductance, the secondary self-inductance and the mutual inductance can be independently controlled using three different resistors. SPICE simulation results are included.
