摘要/Abstract

摘要：

对于多重反馈滤波器提出了一种最小可接受功耗的分析方法.采用劳斯-赫尔维茨稳定性判据对3阶FLFB（Follow-the-Leader-FeedBack）低通滤波器进行分析，当滤波器处于稳定临界状态时，利用MATLAB拟合出最小可接受相位裕度曲线和跨导图，通过电路级分析和验证，给出了滤波器设计参数与功耗之间的关系.采用UMC 40 nm CMOS 工艺进行电路设计，后仿结果表明：滤波器的带宽可调范围为0.9~9.9 MHz，版图面积0.03 mm²，此时总功耗为0.36 mW，与传统采用60°相位裕度的设计相比，功耗减小了近30%.在保证滤波器稳定工作的前提下，降低了功耗，与理论相吻合.

Abstract:

An analysis method about the minimum acceptable power consumption of multiple-loop feedback filter is presented. When a 3^rd follow-the-leader-feedback(FLFB) low pass filter working at the stable state edge, based on Routh-Hurwitz stability criteria, synthesize the minimum acceptable phase margin curve and transconductance figure by MATLAB, and the relationship between filter design parameters and power consumption is given through circuit-level analysis and verification. Design is fabricated in UMC 40 nm CMOS technology, the post-simulation results show that the cutoff frequency is adjustable for 0.9~9.9 MHz, the layout area is 0.03 mm², and the total power consumption is 0.36 mW, reduced nearly 30% compared with the traditional design that phase margin is 60°. Under the premise of ensuring the stable operation of the filter, the power consumption is reduced, confirmed the minimum acceptable power consumption theory.

Key words: low pass filter, minimum acceptable power consumption, follow-the-leader-feedback, stability criteria
