DVCCCTA-Based Implementation of Mutually Coupled Circuit

Abstract

This paper presents implementation of mutually coupled circuit using differential voltage current-controlled conveyor transconductance amplifier (DVCCCTA). It employs only two DVCCCTAs, one grounded resistor, and two grounded capacitors. The primary, secondary, and mutual inductances of the circuit can be independently controlled and tuned electronically. The effect of non-ideal behaviour of DVCCCTA on the proposed circuit is analyzed. The functionality of the proposed circuit is verified through SPICE simulation using 0.25 μm TSMC CMOS technology parameters.

Fractional‐order mutual inductance: analysis and design

“…The port relationships of the DVCCCTA can be written as follows: where R X is the intrinsic resistance at the X terminal and g m is the transconductance from the Z terminal to the O terminal of the DVCCCTA. The circuit realization of the DVCCCTA used in this work is presented in [29]. Routine analysis of the FMCC equivalent circuit illustrated in Figure 8 gives the impedance matrix of (13), which is similar to the impedance matrix of the general case of the FMI given in (5).…”

“…On the other hand, the conventional mutually coupled circuits (MCCs) have a wide range of applications in instrumentation, communications, control systems, signal processing, and modeling . They can also be used for analog filters, particularly for replacing the magnetic transformer in stagger‐tuned filters . Using the MCC in the previous blocks has improved the design flexibility and the system performance.…”

A new electronically tunable mutually coupled circuit using current conveyor transconductance amplifiers (CCTAs)

“…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.…”
