Minimum Component, Electronically Tunable Simulator for Grounded Inductor with Low Parasitic Effects
Keywords:Electronic Control, Grounded Inductor, Inductor Simulator, VDTA,
AbstractA new grounded inductor simulator employing single voltage differencing trans-conductance amplifier (VDTA) and one grounded capacitor has been proposed. The proposed circuit requires minimum number of active and passive elements and offers several advantageous features, which are not simultaneously available with any of the previously reported grounded inductor simulator. The presented configuration provides the electronic tuning of simulated inductance by varying the biasing current of VDTA. Under the influence of VDTA port parasitic impedances, the proposed design offered better performance than the previously reported circuit with similar active and passive component requirements. Further, the high frequency limitation under the non-ideal conditions has been discussed. On non-ideal analysis, the realized circuit was found to be less sensitive as the sensitivity indexes were not more than unity in magnitude. To confirm the working of the proposed circuit as a grounded inductor simulator, it has been used to realize the second order band-pass filter. The performance of realized inductor simulator and band pass filter was demonstrated by SPICE simulations with TSMC CMOS .18μm process parameters.
