A CMOS high performance current differencing buffered amplifier

本文提出了一种利用修改的差分电流传输器（MDCC）与电压跟随器实现的全新高频CMOS差分电流缓冲放大器电路（CDBA）。PSPICE仿真结果表明，在0～100MHz的频率范围内，提出的电路能很好地满足CDBA的端口特性。作为应用，实现了二阶电流模式多功能滤波器，并对他们进行了仿真。

The paper presents a CMOS high performance current differencing buffered amplifier （CDBA）, which is constituted by the modified differencing current conveyor （MDCC） and a voltage follower. The PSPICE simulation results show that from 0 to 100MHz, the proposed circuit meets the port characteristics. As applications, we introduce current-mode multifunction filter, they are demonstrated through PSPICE simulations.
