摘要

本文提出了一种新型接地频率相关负电导(FDNC)模拟器。该模拟器采用两个跨导差分放大器(vdta)和两个接地电容设计。所提出的FDNC模拟器具有实现负电导的电子可控性，不受元件匹配约束，在非理想条件下表现出良好的性能，具有较低的主动/被动灵敏度指标。通过电压型滤波器的设计实例，验证了FDNC仿真器的有效性。通过PSPICE仿真验证了所提电路的性能。

New Frequency Dependent Negative Conductance Simulator employing VDTAs and Grounded Capacitances

This research article proposes a new grounded frequency dependent negative conductance (FDNC) simulator. The presented simulator is designed by employing two voltage differencing trans-conductance amplifiers (VDTAs) along with two grounded capacitances. The presented FDNC simulator enjoys electronic controllability of realized negative conductance with no component matching constraints and exhibits excellent behavior under non-ideal conditions with low active/passive sensitivity indexes. The working of presented FDNC simulator has been verified by some voltage mode filter design examples. The performance of presented circuits has been verified by PSPICE simulations.
