In this paper, synthesis of a complex prototype filter including no inductors and its realization using Second Generation Current Conveyors (CCII's) are proposed. The proposed complex prototype filter is obtained through the frequency shifting method and an equivalent transformation. The proposed complex prototype filter includes no inductors and has fewer nodes connected to imaginary resistors than the conventional one. The proposed filter is compared with the conventional one from the viewpoints of the sensitivity characteristics and the number of the required elements. The frequency response is improved by compensating the parasitic resistors included in CCII's. The validity of the proposed method is confirmed through experiment. © 2021 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.

不包含电感的复杂原型滤波器的合成及其使用 CCII 的实现

在本文中，提出了不包含电感器的复杂原型滤波器的合成及其使用第二代电流传送器 (CCII) 的实现。提出的复数原型滤波器是通过频移法和等效变换得到的。所提出的复杂原型滤波器不包括电感器，并且与传统滤波器相比，连接到虚电阻器的节点更少。从灵敏度特性和所需元件的数量来看，所提出的滤波器与传统滤波器进行了比较。通过补偿包含在 CCII 中的寄生电阻器来改善频率响应。通过实验验证了所提出方法的有效性。© 2021 日本电气工程师学会。由 Wiley Periodicals LLC 出版。
