A nonlinear impedance matching scheme called Synchronized Switch Harvesting on Inductor (SSHI) is highly effective [1]. However, control of the internal capacitor flip timing is complicated to result in a complex controller or suboptimal flip timing. We proposed an active rectifier based on the series SSHI configuration [2]. It ensures an optimal capacitor flip timing, yet the controller is simple to dissipate low power and hence achieve high efficiency. One potential problem of the series SSHI scheme is a non-robust operation due to parasitics and a variety of characteristics of the piezoelectric generators. We present an improved rectifier, which address the problem. The improved rectifier is designed in 0.25 μm BiCMOS process. Post-layout simulation results indicate robust operation and high efficiency of 93%, which is comparable to the original design in [2] and far higher than other existing SSHI rectifiers reported.","PeriodicalId":216613,"journal":{"name":"2015 IEEE 58th International Midwest Symposium on Circuits and Systems (MWSCAS)","volume":"415 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131769387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The special memory behavior of the memristor has been exploited to design control systems, memory arrays, logic gate, and security primitives in previous work. However, the power characteristics of the memristor have not been widely studied yet. In this work, we used a memristor model that is suitable for circuit simulation to investigate the power characteristics of the memristor itself and memristor-based logic gates. Our simulation results indicate that memristor has different power characteristic compared with CMOS devices. The peak power of memristor-based gates does not monotonically increases with input voltage amplitude; instead, the combination of input period length and voltage amplitude determines the occurrence of power peak. The reason is that the power consumption of memristors depends on the effective memristor width, which is controlled by the input. We further examine the feasibility of utilizing memristors to implement a new block cipher, SIMON. Our studies show that the unique power characteristic of memristor based SIMON may add extra challenges for extraction of the secret key from the cipher as it introduces 94% power deviation while power sampling.","PeriodicalId":216613,"journal":{"name":"2015 IEEE 58th International Midwest Symposium on Circuits and Systems (MWSCAS)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127156541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
