Performance Analysis of Tunable Third- and Fifth-Order BandPass Filter Using an Active Inductor

CMOS innovation has turned out to be overwhelming over bipolar innovation for analog circuits design in mixed signal system. CMOS technology has become dominant over bipolar technology for analog circuits. So proposed active floating inductor and active load resistor is used for the implementation of third- and fifth-order bandpass filter. Proposed active floating inductor is designed with CMOS and current sources. The tunability can obtain by varying the transconductance of inductor which in turn is controlled by the externally controlled bias current and bias voltage. Simulation results show that proposed bandpass filter will provide a large bandwidth and less power consumption than the filter designed with conventional inductor. In this paper, the simulations are obtained by using 65 nm CMOS technology on Tanner EDA tool 13.0.
