摘要

提出了一种采用1 /spl mu/m MOS技术设计的二阶Gm-C滤波器。该滤波器的主要特点是高线性度和在5v电源下的低功耗工作。该电路采用MOS栅极电容作为滤波器。电路性能显示，在1mhz下，1伏(pk-pk差分)的THD为55db。过滤器的面积是320平方英尺。密耳。功率损耗为18mw。

A low power video frequency continuous time filter

A second order Gm-C filter designed in 1 /spl mu/m MOS technology is presented. The main characteristics of the filter are high linearity and low power operation at 5 V supply. This circuit uses MOS gate capacitance for the filter. Circuit performance shows a THD of 55 dB for 1 volt (pk-pk differential) at 1 MHz. The area of the filter is 320 sq. mils. and its power dissipation is 18 mW.
