By using the ultra-low-voltage multiplier with digital control and simple one-cycle variable frequency technique, the converter realizes fast power tracking and high conversion efficiency, and minimizes the power consumption and harmonics, thereby obtaining high tracking precise and low total harmonic distortion (THD). Implemented in 65-nm CMOS process, this converter achieves 85.9% peak power efficiency with dc output voltage of 1.6[Formula: see text]V. The peak tracking efficiency and THD are 99.2% and 1.3%, respectively. The peak output power is 18.31[Formula: see text][Formula: see text]W, and the power loss of the entire converter is only 16.53[Formula: see text][Formula: see text]W. <\/jats:p>","DOI":"10.1142\/s0218126617501766","type":"journal-article","created":{"date-parts":[[2017,3,28]],"date-time":"2017-03-28T23:05:36Z","timestamp":1490742336000},"page":"1750176","source":"Crossref","is-referenced-by-count":2,"title":["A Novel Interface Circuit with 99.2% MPPT Accuracy and 1.3% THD for Energy Harvesting"],"prefix":"10.1142","volume":"26","author":[{"given":"Yani","family":"Li","sequence":"first","affiliation":[{"name":"Institute of Microelectronics, Xidian University, No.2 Taibai South Road, Xi\u2019an, 710071, P.
