A traditional two-stage active rectifier is adopted, which includes a first-stage negative voltage converter and an active diode. A comparator with offset control technique is proposed; thus the input-referred offset voltage of the proposed comparator can be less than 1[Formula: see text]mV. The current detected accuracy of the proposed offset-controlled comparator (OCC) is improved by more than 10 times over a traditional comparator. Output oscillations of the OCC are dramatically reduced attributing to the high precision of current detection. In addition, the OCC is also able to prevent the reverse leakage current. The design is implemented in an SMIC 0.18[Formula: see text][Formula: see text]m standard CMOS technology with a chip area of 0.22[Formula: see text]mm<jats:sup>2<\/jats:sup>. The measurement results show that the maximum output power, power conversion efficiency and figure of merit are 23.3[Formula: see text][Formula: see text]W, 90%, and 0.9, respectively, when the open-circuit voltage is 2.4[Formula: see text]V. The proposed rectifier can be self-powered without the additional external supply. <\/jats:p>","DOI":"10.1142\/s0218126618500792","type":"journal-article","created":{"date-parts":[[2017,9,14]],"date-time":"2017-09-14T04:16:01Z","timestamp":1505362561000},"page":"1850079","source":"Crossref","is-referenced-by-count":3,"title":["A Power-Enhanced Active Rectifier with Offset-Controlled Comparator for Self-Powered PEH Systems"],"prefix":"10.1142","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9897-5361","authenticated-orcid":false,"given":"Lianxi","family":"Liu","sequence":"first","affiliation":[{"name":"School of Microelectronics, Xidian University, 2 Taibai Road, Xi\u2019an, Shaanxi, P.
