Eight new immittance function simulators (IFSs) with only grounded passive elements are proposed in this paper. All of the IFSs consist of only two DVCC+s and a minimum number of passive components without needing any passive element matching constraints. Each of the proposed IFSs can provide one of ±L with series ±R and ±L with parallel ±R. As an application example, a second-order mixed-mode (MM) multifunction filter is developed from the proposed +L with series +R and +L with parallel +R. Furthermore, a proportional integral derivative (PID) controller is derived from the proposed +L with series +R. Many simulation results through the SPICE program and several experimental ones are included to verify the theory.

基于 DVCC+ 的导抗函数模拟器，仅包括接地无源元件

本文提出了八种仅具有接地无源元件的新导抗函数模拟器 (IFS)。所有 IFS 仅由两个 DVCC+ 和最少数量的无源元件组成，无需任何无源元件匹配约束。每个提议的 IFS 都可以提供±L带系列±R 和±L 带并联±R. 作为一个应用示例，二阶混合模式 (MM) 多功能滤波器是从提议的 +L 与串联 +R 和 +L 与并联 +R 开发的。此外，比例积分微分 (PID) 控制器源自建议的 +L 与系列 +R。通过 SPICE 程序的许多模拟结果和几个实验结果被包括在内以验证理论。
