However, its scope of application and integration as a replacement of diode rectifier is handicapped by the compulsory requirement of external sensing and gating circuits needed for precise ON/OFF timing control and the tedious incorporation to be a dependent part of the overall converter circuit. We report a unique smart-power synchronous rectifier (SPSR) that is a two-terminal diode-alike power-integrated circuit building block that provides ultralow on-state voltage rectification without the need of adding any external sensing and gating control. Therefore, a direct replacement of diode rectifier by the SPSR in any converter circuit is made possible. In this paper, the design and fabrication of a fully CMOS-process compatible SPSR device is presented. The fabricated device achieved a low forward voltage of 0.14 V in comparison with 0.75 V of the body diode at the same rated-current density. It has a low specific input capacitance of 11.8 nF/cm2, which makes it suitable for megahertz switching operations. This reported SPSR is CMOS-fabrication-process compatible and can be directly integrated with any power converter circuits on the silicon substrate. © 2010 IEEE.||Source Title:||IEEE Transactions on Power Electronics||URI:||http://scholarbank.nus.edu.sg/handle/10635/81914||ISSN:||08858993||DOI:||10.1109/TPEL.2010.2049586|
