摘要

提出了一种基于CMOS 130nm工艺的无源低通滤波器。该滤波器具有椭圆传递函数，能以最低阶提供最锐利的带外抑制。该滤波器的带宽范围从直流到6GHz，适用于宽带零中频接收机架构。该滤波器具有平衡实现，以便与平衡混频器集成，并在7.7GHz时显示18 dB插入损耗。对该布局进行了全波仿真，并与实测结果进行了比较，结果吻合良好。

A DC to 6 GHz balanced elliptic low-pass filter in CMOS 130nm technology

A passive low-pass filter on CMOS 130nm process is presented in this paper. The filter has an elliptic transfer function to give the sharpest out of band rejection with the lowest order. The bandwidth of the filter is from DC to 6GHz which makes it applicable to wide band zero IF receiver architectures. The filter has a balanced implementation in order to be integrated with a balanced mixer and shows 18 dB insertion loss at 7.7GHz. Full-wave simulations of the layout are presented together with the measurement results and show excellent agreement.
