提出了电流模电路中的一个通用积木块———伴随运放。用它能把基于电压运放的电压模电路转换成电流模电路。分析了理想伴随运放的特点和应用 ,提出一种CMOS伴随运放电路 ,介绍了用它设计的电流模滤波器。
A common building block in the current mode circuit is proposed - along with the op amp. Use it to convert voltage mode op amp based on voltage op amp into current mode circuit. The characteristics and applications of the ideal accompanying op amp are analyzed. A CMOS accompanying op amp circuit is presented and the current mode filter designed by it is introduced.
