Abstract: This article presents a tunable Synthetic Transformer (ST) namely Mutually Coupled Circuit (MCC) based on Current Conveyor Transconductance Amplifier (CCTA). The proposed circuit consists of two CCTA, three resistors, two capacitors and four MOS switches and can be configured in four different pairs of mutual coupled circuit through appropriate setting of MOS switches. The proposed ST does not require component matching condition. Self-inductance, mutual inductance, and resonant frequency can be tuned by bias current of CCTA. Furthermore, non-ideal effects on the proposed ST are discussed. Performance of the proposed circuit is evaluated by pre-layout and post-layout simulation using 90 nm CMOS process technology. A double tuned band pass filter is shown as an application. The impact of supply voltage and temperature variation is examined and a maximum deviation of 3.326% and 16.8% respectively are observed in resonant frequency of DTBPF. The effect of component variations is also studied through Monte Carlo analysis. The output noise spectral density of DTBPF at resonant frequency is observed to be 102.489 nV/sqrt (Hz) whereas the total harmonic distortion is observed within 1.3% for peak input voltage range 0.05 V–3.5 V. The power consumption of DTBPF circuit is 5.16 mW at 100 μA bias current of CCTA. • This article presents a tuneable synthetic transformer namely mutually coupled circuit based on Current Conveyor Transconductance Amplifier (CCTA). • The proposed circuit follows the dot convention of a passive transformer and produces all four pairs of mutually coupled circuit like passive transformers by an appropriate setting of MOS switches. • Non-ideal effects of CCTA on the proposed ST are analysed mathematically. • Performances of the proposed circuit are evaluated by pre-layout and post-layout simulation using 90 nm CMOS process technology. • Monte Carlo analysis, temperature variation analysis, noise analysis, supply voltage variation analysis, and total harmonic distortion of the frequency response of a double tuned band pass filter are evaluated with supporting results.
