摘要

提出了一种工作在高Q值下、采用子采样和直接数字调谐的增Q滤波器。该滤波器适用于蓝牙或GPS等应用中的中频滤波器。该滤波器工作电压为1.2V - 1.8V，在500MHz时功耗为1.08 mW，在1.5V时SFDR为37 dB, Q为650。

A 0.18/spl mu/m CMOS, high Q-enhanced bandpass filter with direct digital tuning

A Q-enhanced filter is presented which operates at a high Q and employs sub-sampling and direct digital tuning. The filter is suitable as an IF filter in applications such as Bluetooth or GPS. The filter operates from 1.2V - 1.8V and consumes 1.08 mW at 500MHz with a SFDR of 37 dB and a Q of 650, at 1.5V.
