In this paper a review on design perspective of current-mode current differential trans-conductance amplifier (CDTA) is presented for the state of the art analog signal processing/generating modules design as the main objective. The CDTA circuits are classified according to the active element used for the design with all related parameters taken into consideration. Likelihood implementations of different analog signal processing/generating modules are covered and a comparison of their main parameters trans-conductance, bandwidth, port impedances and power consumption is given. The feasibility of implementing with a lesser area is also considered from the VLSI design viewpoint. The review concludes with CDTA structures with the best possible parameters obtained and future possibilities.

本文以电流模式电流差分跨导放大器（CDTA）的设计视角为主要目标，对现有技术的模拟信号处理/生成模块设计进行了综述。根据用于设计的有源元件，将CDTA电路分类，并考虑所有相关参数。涵盖了不同模拟信号处理/生成模块的可能实现方式，并对它们的主要参数跨导，带宽，端口阻抗和功耗进行了比较。从VLSI设计的角度出发，还考虑了以较小的面积实现的可行性。审查总结了具有最佳参数和未来可能性的CDTA结构。
