摘要

介绍了两种二阶滤波器结构及其在双端和单端多输入放大器配置中的应用。这些电路可以配置为执行BP, HP, LP和陷波滤波器功能。基于复合折叠级联码(CFC)的全互补放大器测试结构的Gm可调谐性是通过在高兆赫范围内中心频率变化的MOSR方案实现的，使用/spl plusmn/2.5 V电源。

Versatile second order filter structures for low-voltage multiple-input amplifiers

Two second order filter architectures are presented with applications to double and single ended multiple input amplifier configurations. These circuits can be configured to perform BP, HP, LP and notch filter functions. The Gm tunability of the fully-complementary, Composite Folded Cascode (CFC) based amplifier test structures is achieved by a MOSR scheme with center-frequency variations in the upper Megahertz range, using power supplies of /spl plusmn/2.5 V.
