该论文提出了一种压电能量收集接口电路，通过全自主共轭阻抗匹配和156%的扩展带宽，实现了低功耗（0.38μW）和高效率的能量收集。系统通过测量激励频率选择最优时间延迟组合，减少了参数数量，并在89.1-90.5Hz频率范围内通过近似最优设置实现类似效果。
of t1/t2 to approximate the optimal t1/t2 as closely as possible. The system measures the excitation frequency to decide which combination to use. This design greatly reduces the number of t1/t2 parameters to only 6 (Fig. 8.7.1) by accepting a lower power at certain frequency bands, but enabling the adjustment of the time delays by trimming a limited number of passive components. In the frequency range from 89.1 to 90.5Hz, the presented setting t1=0ms causes no phase shift, while the optimal setting (5.1 to 5.5ms) delays the system by nearly half a cycle, resulting in a similar effect. 1 2 Harvesting energy from ambient vibrations with piezoelectric transducers is an alternative solution for the surging needs of self-powered devices, such as IoT
