Simulation of ideal grounded tunable inductor and its application in high quality multifunctional filter
Abstract
Purpose
Aims to present a simple circuit for the realization of electronically tunable ideal grounded inductor, which consists of two current controlled conveyors along with a grounded capacitor. Also its application for realization of multifunctional filter is demonstrated.
Design/methodology/approach
Multifunctional filter (low pass, band pass and high pass filters) is designed using proposed grounded inductor realization which provides standard responses without any constrains in terms of matching conditions.
Findings
The multifunctional filter designed using the proposed realization has many attractive features such as low component count, high‐Q, low sensitivity performance, independent Q‐tuning of the filter without affecting its pole frequency.
Originality/value
Simulation results show excellent performance with low power consumption of 1.87 mW at ±2.5 supply voltage.
