Efficient low-voltage low-power Converters for Self Powered Microsystems (SPMS) based on 0.13μm technology

摘要

In Self Powered Microsystem (SPMS) architecture based on a Mico Power Generator there are two main electrical circuits: an AC/DC converter and a DC/DC converter, which converts the available energy in the environment to a suitable electrical form to use in electronic circuits. Three AC/DC rectifiers designed in 0.13μm technology are presented in this paper in the frame of low voltage and low power applications. Two of them are synchronous rectifiers and the last one is based on a typical PN junction. The features of each rectifier are verified by simulation in terms of conversion efficiency. Finally, to define the SPMS system, an application with the best synchronous rectifier and an inductorless DC/DC charge-pump regulator is presented.
