Electronically Tunable Grounded Capacitance Multiplier

Abstract

This paper presents a novel low-power, electronically tunable, temperature-insensitive and a high multiplication factor grounded capacitance multiplier, based on third-generation current conveyor transconductance amplifier (CCIIITA). The proposed circuit consists of a single CCIIITA block and a grounded capacitor making it suitable from integrated circuit realization viewpoint. Also, the proposed design refrains from utilizing any passive components and puts no restriction on component values. The proposed design is supported by the SPICE simulations and experimental results. Also, a band-reject filter with notch frequency of 1 kHz, which comes under the voice frequency range, is realized as an application.

KEYWORDS:

• Band-reject filter
• Electonically tunable
• Gounded capacitance multiplier
• Passive components
• Third-generation current conveyor transconductance amplifier
