摘要

提出了一种采用3 μ m工艺实现的截止频率为110MHz的CMOS三阶椭圆低通滤波器。该滤波器由差动跨导元件和电容组成。由于没有内部节点，该跨导元件具有良好的线性特性和优异的高频性能。截止频率和q因子都可以调谐。

A 110MHz CMOS Transconductance-C Low-Pass Filter

A CMOS third order elliptic low-pass filter with a 110MHz cut-off frequency realized in a 3¿m-process is presented. The filter consists of differential transconductance elements and capacitors. The transconductance element has good linearity properties and an excellent high frequency behaviour thanks to the absence ofinternal nodes. Both the cut-off frequency and the Q-factors can be tuned.
