Single element based-novel temperature insensitive/electronically controllable floating capacitance multiplier and its application

摘要

This article introduces floating capacitance multiplier using differential voltage current conveyor transconductance amplifiers (DV-CCTA). Its outstanding feature is that the capacitive value can be widely adjusted by input bias currents of the DV-CCTA and is theoretically temperatureinsensitive. The circuit construction consists of only single DV-CCTA, with a grounded capacitor. The circuit performances are depicted through PSPICE simulations. They show good agreement to theoretical anticipation. Power consumption is approximately 0.48mW. Increasing capacitance and an application as a fourth-order Chebyshev high-pass filter are included to confirm the usability of the proposed circuit.
