A novel three-step startup procedure is proposed and applied on the boost converter, which makes the converter start up with a below-threshold voltage. Besides, adaptive on-time control method can reduce the output ripple dramatically. The proposed integrated boost converter is designed in an SMIC 0.18-[Formula: see text]m standard CMOS process and occupied a chip area of [Formula: see text][Formula: see text]mm<jats:sup>2<\/jats:sup> without any low-[Formula: see text] MOSFETs. In the adopted process, the threshold voltages of PMOS and NMOS are [Formula: see text]0.45[Formula: see text]V and 0.48[Formula: see text]V, respectively. The simulation results show that the proposed converter can start up successfully at the input voltage of 0.25[Formula: see text]V, the output voltage is 1.8[Formula: see text]V with the ripple less than 33[Formula: see text]mV, and the peak efficiency can be up to 94.7%. <\/jats:p>","DOI":"10.1142\/s0218126618501207","type":"journal-article","created":{"date-parts":[[2017,11,21]],"date-time":"2017-11-21T03:13:11Z","timestamp":1511233991000},"page":"1850120","source":"Crossref","is-referenced-by-count":1,"title":["Adaptive On-Time-Controlled PFM Boost Converter with a Below-Threshold Startup Voltage"],"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 South Taibai Road, Xi\u2019an, Shaanxi 710071, P.
