摘要

在0.13 μ m CMOS技术下，实现了IEEE802.11 n的带质量因子(Q)调谐电路的五阶LPF。提出的Q调谐技术可实现19.7 MHz有源rc切比雪夫LPF。该滤波器具有2 dB增益，30 nV/Hz1/2输入参考噪声，113 dB muV输入PIdB，从1.5 V电源吸收7.5 mA电流，占地面积为0.2 mm2。

A 19.7 MHz, 5th Order Active-RC Chebyshev LPF for IEEE802.11n with Automatic Quality Factor Tuning Scheme

A fifth order LPF with a quality factor(Q) tuning circuit has been implemented for IEEE802.11 n in a 0.13 mum CMOS technology. The proposed Q tuning technique enables a 19.7 MHz, active-RC Chebyshev LPF. The filter has 2 dB gain, 30 nV/Hz1/2 input referred noise, 113 dB muV input PIdB, draws 7.5 mA current from 1.5 V supply and occupies an area of 0.2 mm2.
