Abstract :
This paper describes a simple circuit configuration for realizing an impedance multiplier using VDTAs (voltage differencing transconductance amplifier) as active components. The proposed impedance multiplier circuit contains only two VDTAs along with external impedance under control. The equivalent value of the realized multiplier can be tuned electronically through the transconductance parameters of the VDTAs. The characteristic of the proposed circuit is demonstrated using PSPICE simulation with TSMC 0.35-μm CMOS technology.
