Process and Voltage Variation-Aware Design and Analysis of Active Grounded Inductor-Based Bandpass Filter

An active inductor based on voltage differencing voltage transconductance amplifier (VDVTA) as an active element is presented. Using the active inductor, a bandpass filter is designed and the effect of process and current variations on the characteristics of the active grounded inductor-based bandpass filter is demonstrated. The bandpass filter shows its robustness against process and current variations. The simulation of the presented circuit is done using Virtuoso Analog Design Environment of Cadence @ 45-nm CMOS model parameters.
