Abstract

In this Letter, we propose a novel current-mirror-based lossless integration stage. The proposed stage is derived from the lossy integration counterpart by simply incorporating an additional DC current source. The unique offered contribution is the reduction of the circuit complexity in the resulting current-mode systems, where the introduced integrator is utilized. This is verified through the performed comparison with the corresponding stage, which is already introduced in the literature. A multiple-output biquad filter is designed using the proposed lossless integrator, and its performance is evaluated through the utilization of the Cadence IC design suite.

降低电路复杂度的基于电流镜的滤波器

在这封信中，我们提出了一种新的基于电流镜像的无损集成阶段。所建议的阶段是通过简单地合并一个额外的直流电流源而从有损积分对应物中推导出来的。独特的贡献是减少电路的复杂性，在产生的电流模式系统，其中引入的积分器被利用。这是通过与相应阶段的执行比较来验证的，这在文献中已经介绍过。利用所提出的无损积分器设计了一个多输出双路滤波器，并利用Cadence IC设计套件对其性能进行了评估。
