VDTA BASED GROUNDED TO FLOATING ADMITTANCE ELECTRONICALLY CONVERTER

In this article, a new grounded to floating admittance convertor employing only two voltage differencing transconductance amplifiers (VDTAs) has been suggested. The proposed configuration is able to convert any arbitrary grounded admittance into floating admittance without any requirement of additional passive element. The equivalent floating admittance value can tuned electronically through VDTA transconductance. Depending on the passive element selection, the presented topology can simulate active floating resistor and floating capacitor. The presented circuit does not require any active/passive component matching constraints; it has low sensitivity values and good non-ideal behavior. The influence of VDTA port parasitic on proposed configuration is also investigated. The validity of proposed circuit is verified by some application examples. VDTA based Grounded to Floating Admittance converter is implemented & simulated with PSPICE using the 0.18um CMOS technology.
