摘要
本文主要介绍了一种应用于Cascode结构运放中的开关电容共模负反馈电路,它具有稳定性好、对运放频率特性影响小、不消耗额外功率等优点。对电路运用Hspice进行了模拟,并给出了模拟结果。
A dynamic switched capacitor common mode feedback circuit which is useful to Cascode differential operational amplifier is introduced. This circuit is stable with little influence on frequency characteristics and without extra power dissipation. This circuit has been verified by computer simulation using HSPICE with satisfactory results.
