摘要

设计了一个可调谐的三阶巴特沃斯低通滤波器，其芯片面积为小型化的0.033 mm2，并将其集成在65nm CMOS宽带收发器RFIC中，用于多模式通道选择。采用紧凑的二进制加权电流模式输出OTA，该滤波器具有13.3至53.6 MHz的数字可编程截止频率。测量结果表明，在1.2 V电源的功耗为4.7-8.4 mW时，带内IIP3为19-21 dBm，输入参考噪声为33-38 nV/√Hz。

A 0.033mm2 Integrated Tunable Low-Pass Filter for Wideband Transceiver RFIC in 65 nm CMOS

A tunable 3rd-order Butterworth low-pass filter occupying a miniaturized 0.033 mm2 chip area is designed and integrated as a building block in a 65 nm CMOS wideband transceiver RFIC for multi-mode channel selection. Using compact binary-weighted current mode output OTA, the filter exhibits digitally programmable cutoff frequencies from 13.3 to 53.6 MHz. Measurement results show an in-band IIP3 of 19–21 dBm, and an input-referred noise of 33–38 nV/√Hz at a power consumption of 4.7-8.4 mW from a 1.2 V supply.
