AI中文摘要：
忆阻器在神经形态计算和存内计算中可实现高达1000倍的能耗降低，但其在电力转换器控制中的整合仍不完善。现有实现方案要么将忆阻器输出转换为数字信号用于基于数字信号处理器（DSP）的脉宽调制（PWM），重新引入计算开销；要么使用可编程性有限的模拟PWM电路。由于PWM生成是电力转换器控制的最终必要阶段，需要可编程的基于忆阻器的PWM电路以充分发挥忆阻计算的能效优势。本文提出一种用于开关电力转换器的可编程基于忆阻器的PWM电路，工作频率约为200千赫兹，该设计结合了数字控制器的可编程性与模拟PWM发生器的低功耗特性。采用商用忆阻器进行实验验证，实现了144.7千赫兹至204.2千赫兹的可编程开关频率；与电力转换器控制中常用的DSP实现相比，所提设计实现了92%的能耗降低。
英文摘要：
Memristors can achieve up to a 1000-times reduction in energy consumption in neuromorphic and in-memory computing, but their integration into power converter control remains incomplete. Existing implementations either convert memristor outputs into digital signals for DSP-based pulse-width modulation (PWM), reintroducing computational overhead, or use analog PWM circuits with limited programmability. Since PWM generation is the final essential stage of power converter control, a programmable memristor-based PWM circuit is needed to fully realize the energy-efficiency benefits of memristive computing. This paper presents a programmable memristor-based PWM circuit operating at approximately two hundred kilohertz for switching power converters. The design combines digital-controller programmability with the low power consumption of analog PWM generators. Experimental validation using commercially available memristors achieves a programmable switching frequency from 144.7 kHz to 204.2 kHz. Compared with a commonly used DSP implementation in power converter control, the proposed design achieves a 92% reduction in power consumption.
