Abstract

A band-pass filter operating in 2.40 GHz to 2.48 GHz range is designed in 0.18 μm CMOS technology. It has tunable center frequency, Q-factor and gain. The fully integrated system-on-chip (SOC) 10th order band-pass filter is built by cascading five stages of 2nd order. The simulation of the filter on ADS software provides an insertion gain of 8 dB in the pass-band frequency from 2.40 GHz to 2.48 GHz. The attenuation in the stop-band is observed to be higher than 50 dB at 400 MHz away from pass-band edge with 15 mA current sinking from a 1.8 V supply. We present several simulation results to highlight these characteristics.
