A VDVTA-Based Novel Configuration for Realizing Grounded Inductance

This paper proposes a new active simulator of grounded inductance using single voltage differencing voltage transconductance amplifier (VDVTA), one grounded capacitor and one grounded resistance. The presented configuration is electronically controllable, exhibits low nonideal effects and has low values of active and passive sensitivity. The working of the presented active inductor simulator is confirmed by employing it in designing of a voltage mode (VM) band-pass biquad filter. The performance of proposed inductor simulator and band-pass filter is demonstrated by SPICE simulations with TSMC CMOS 0.18 µm process parameters.
