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.
Highlights
Since the beginning of current-mode circuit concept, a lot of research has been directed towards the development of active inductance and immittance simulator circuits
Gorski Popiel technique is outlined which is followed by realieation of the proposed DVCCCTA-based floating mutually coupled circuit
To verify the functionality of the proposed DVCCCTAbased mutually coupled circuit (MCC), SPICE simulations have been carried out using TSMC 0.25 μm CMOS process model parameters and power supplies of VDD = −VSS = 1.25 V and VBB = 0.8 V
Summary
Since the beginning of current-mode circuit concept, a lot of research has been directed towards the development of active inductance and immittance simulator circuits. The study of MCC simulators [1–8] shows that the circuits reported in [1, 2, 7] are based on operational transconductance amplifier (OTA), [2,3,4] that uses second-generation current conveyors (CCII), [5, 6] employ second-generation current-controlled conveyors (CCCII), [7] uses differential voltage current conveyors (DVCC) and CCIIs, [8] and utilizes current-controlled current backward transconductance amplifier (CC-CBTA). A new DVCCCTA- [9] based MCC is proposed that uses Gorski Popiel Technique [10] It is floating in nature and uses only two DVCCCTAs, one resistor, and two grounded capacitors. The theoretical proposition has been verified with SPICE simulations using the parameters of 0.25 μm TSMC CMOS Technology
