Abstract

A CMOS 80–400 MHz 5TH 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.

一个80 - 400mhz 74 dB-DR Gm-C低通滤波器，具有独特的自动调谐系统

提出了一种具有独特自动调谐系统的80 - 400mhz 5阶切比雪夫Gm-C低通滤波器。该滤波器采用TSMC 0.13-μm RF CMOS工艺设计制作。实验结果表明，该滤波器的截止频率可在80 ~ 400 MHz之间进行调谐，调谐步长小于7MHz，平均调谐误差为3.6%。该滤波器还实现了0-30 dB的增益，16.5 dBm的IIP3和14-18 dB的NF。该滤波器在THD小于1%时的动态范围为74 dB。在1.2 V供电电压下，功耗仅为9mw。
