Two new simple and effective voltage mode frequency selective structures that pass all signals are proposed and explored in this paper. The proposed structures use a single active element and three passive components in each. Dual-X second generation current conveyor (DXCCII) is employed as an active element along with two resistors and a capacitor as passive elements. The capacitor is grounded which goes well with the IC fabrication requirements. Both the structures offer low active and passive sensitivities. The presented structures also exhibit the feature of high input impedance. A comprehensive study of device non-idealities and parasitic is also included to highlight the non-ideal performance of the presented ideas. In addition, to prevent the use of passive resistors, resistor less realizations of proposed structures are also explored by replacing the passive resistors with MOS-based active resistors. A quadrature oscillator is also presented as one of the possible applications of the proposed frequency selective structures. Simulations results are in match with the theoretically analyzed performance.

全通频率选择结构：模拟领域的应用

本文提出并探索了两种新的简单有效的可通过所有信号的电压模式频率选择结构。建议的结构使用单个有源元件和每个中的三个无源元件。Dual-X 第二代电流传输器 (DXCCII) 用作有源元件，两个电阻器和电容器用作无源元件。电容器接地，符合 IC 制造要求。两种结构都提供低主动和被动灵敏度。所提出的结构还表现出高输入阻抗的特点。还包括对器件非理想和寄生的综合研究，以突出所提出想法的非理想性能。此外，为防止使用无源电阻，通过用基于 MOS 的有源电阻器替换无源电阻器，还探索了所提出结构的无电阻器实现。正交振荡器也被提出作为所提出的频率选择结构的可能应用之一。仿真结果与理论分析的性能相符。
