摘要

提出了一种基于源跟随器的可调谐带阻滤波器。该滤波器采用源从动器架构，采用部分正反馈和前馈路径，采用0.18µm CMOS技术。该滤波器在1.8V电源下消耗约1.4 mW，中心频率设计为1.5GHz，带宽为360 MHz，衰减为80 dB。该滤波器在1.495GHz和1.505 GHz两个音调下达到10 dBm IIP3。

A Tunable Bandstop Filter Based on Source Follower

A tunable bandstop filter based on source follower is presented. The filter is designed using a source follower architecture with partial positive feedback and feed-forward paths using 0.18µm CMOS technology. The filter consumes about 1.4 mW from a 1.8V power supply, and it is designed to have 1.5GHz center frequency with 360 MHz bandwidth and 80 dB attenuation. The filter achieves 10 dBm IIP3 for two tones at 1.495GHz and 1.505 GHz.
