Impact of Temperature Variation on Resonant Frequency of Active Grounded Inductor-based Bandpass Filter


Objective: This paper proposes an electronically tunable active grounded inductor circuit using VDVTA as a new active element. The circuit can replace spiral passive inductors for all Analog Signal Processing and data communications operations. Method/Analysis: The impact of temperature variation on its resonant frequency is investigated using Virtuoso Analog Design Environment of Cadence @ 45-nm CMOS technology node. Findings: This paper carries out a study on CMOS realization of Voltage Differencing Voltage Transconductance Amplifier (VDVTA) and its application as an active grounded inductor. A Bandpass filter circuit is realized using the VDVTA based grounded inductor. Furthermore, the impact of temperature variation on the response of the bandpass filter is analyzed and presented. Novelty/Improvement: The proposed circuit uses only active elements and a grounded capacitor. Due to this, the circuit finds applications in all canonical operations and integrated circuit implementations.
Keywords: Active Inductor, Bandpass Filter, Volatge Differencing Voltage Transconductance Amplifier (VDVTA)
