Abstract

A CMOS 80-400 MHz 5^TH order Chebyshev Gm-C low-pass filter with a unique auto tuning system is presented. The filter was designed and fabricated with TSMC 0.13-μm RF CMOS process. Experimental results show that the cut-off frequency of the filter can be tuned between 80-400 MHz, with a tuning step less than 7MHz and an average tuning error of 3.6%. The filter also realizes gain of 0-30 dB, IIP3 of 16.5 dBm and NF of 14-18 dB. Dynamic range of the filter for THD less than 1% is 74 dB. Power dissipation is only 9 mW with 1.2 V supply voltage.
