摘要

本文提出了一种新的混合模式通用滤波器结构,能够工作在电压和跨阻模式下。所提出的单滤波器配置可以数字化地重新配置,以实现在单个输出端口上的所有五种二阶滤波器功能(类型)。所提出的配置的其他显著特征包括独立可编程的滤波器参数,全级联性和低灵敏度数字。然而,所有这些功能都是以大量活动元素为代价提供的。它需要三个数字可编程电流反馈放大器和三个数字可编程电流传送带。通过介绍三种额外的简化硬件混合模式通用滤波器配置及其与已有滤波器的比较,证明使用六个有源元件是合理的。

Reconfigurable Mixed Mode Universal Filter
This paper presents a novel mixed mode universal filter configuration capable of working in voltage and transimpedance mode. The proposed single filter configuration can be reconfigured digitally to realize all the five second order filter functions (types) at single output port. Other salient features of proposed configuration include independently programmable filter parameters, full cascadability, and low sensitivity figure. However, all these features are provided at the cost of quite large number of active elements. It needs three digitally programmable current feedback amplifiers and three digitally programmable current conveyors. Use of six active elements is justified by introducing three additional reduced hardware mixed mode universal filter configurations and its comparison with reported filters.
