Abstract :
This paper presents the analysis, the efficiency optimization and the design strategy of a Dickson type rectifier using 65nm CMOS technology. The rectifier is used as an on-chip wireless power receiver for wireless power transfer applications. The modeling of this rectifier takes the threshold voltage variation, bulk modulation, and the major parasitic capacitors into account. A mathematical model of the rectifier allows finding the relationship between its performance and the design parameters. Based on parameter discussion and performance analysis, a design procedure is presented to get higher conversion efficiency.
