A current-mode first-order filter configuration simultaneously providing noninverting and inverting low-pass (LP) and high-pass (HP) responses depending on passive element choice is proposed. In addition, all-pass filter (APF) responses can be easily obtained with interconnection of LP and HP output currents. The proposed filter employs only two differential voltage current conveyors, a grounded resistor and a grounded capacitor, so it is suitable for integrated circuit realization. It provides the feature of high output impedance. It does not need any passive element matching constraints. A voltage-mode oscillator based on the inverting APF is presented as a typical application. The performance of the proposed configuration is verified through many SPICE simulation and experimental test results.

基于 DVCC 的电流模式一阶通用滤波器

提出了一种电流模式一阶滤波器配置，可根据无源元件的选择同时提供同相和反相低通 (LP) 和高通 (HP) 响应。此外，通过 LP 和 HP 输出电流的互连可以轻松获得全通滤波器 (APF) 响应。所提出的滤波器仅采用两个差分电压电流传输器，一个接地电阻器和一个接地电容器，因此适用于集成电路实现。它提供了高输出阻抗的特性。它不需要任何被动元素匹配约束。基于反相 APF 的电压模式振荡器是一个典型应用。通过许多 SPICE 仿真和实验测试结果验证了所提出配置的性能。
