Abstract

In this work, a single active element (Extra-X Current Controlled Conveyor) with grounded capacitor is used to design a reconfigurable first-order universal filter (CFUF). By simply swapping the digital control words (k₁k₂), the suggested circuit may implement all of the common filter responses, including high-pass, low-pass, and all-pass. An EX-CCCII serves as the active element in the filter setup, which is based on a novel topology, which provides several advantages, such as reduced complexity, low power consumption, and improved performance. The following advantages of the proposed circuit: high input impedance for voltage input signals, electronically controllable pole frequency that varies with bias current, and a single grounded capacitor that can be integrated into an IC. At a power supply level of ±0.5 V, the proposed circuit is modeled using specifications for 0.18-micrometer CMOS technology. PSPICE simulation tool is used to demonstrate the filter’s performance.

使用单个 EX-CCCII 设计可配置的一阶通用滤波器

摘要在这项研究中，我们利用带有接地电容器的单个有源元件（Extra-X 电流控制传送带）设计了一种可重新配置的一阶通用滤波器（CFUF）。通过简单地交换数字控制字（k1k2），所建议的电路可以实现所有常见的滤波器响应，包括高通、低通和全通。EX-CCCII 作为滤波器设置中的有源元件，基于新颖的拓扑结构，具有降低复杂性、低功耗和提高性能等优点。该电路具有以下优点：电压输入信号的输入阻抗高；极点频率可随偏置电流变化而进行电子控制；只需一个接地电容器即可集成到集成电路中。在 ±0.5 V 的电源电平下，建议的电路采用 0.18 微米 CMOS 技术规格建模。PSPICE 仿真工具用于演示滤波器的性能。
