Abstract

This article presents the modeling and optimization of a sense-and-set (SaS) rectifier. The basic equations governing the operation of a SaS rectifier are derived analytically using Laplace-transform techniques. An expression for the harvesting efficiency of a SaS rectifier is developed by evaluating the conduction and gate-drive losses as well as the output power of the rectifier. The derived expressions are then employed to locate the optimal design point of a SaS interface circuit. The proposed modeling approach reduces the required run time by more than 2000 times as compared to SPICE simulation without sacrificing accuracy. The following design parameters are determined for maximum efficiency: optimal relative size between the rectifier switches, total conductance of the rectifier, and sensing frequency. The close match between the theoretical expressions and circuit simulation results validates the proposed analysis.

期刊介绍： The IEEE Transactions on VLSI Systems is published as a monthly journal under the co-sponsorship of the IEEE Circuits and Systems Society, the IEEE Computer Society, and the IEEE Solid-State Circuits Society. Design and realization of microelectronic systems using VLSI/ULSI technologies require close collaboration among scientists and engineers in the fields of systems architecture, logic and circuit design, chips and wafer fabrication, packaging, testing and systems applications. Generation of specifications, design and verification must be performed at all abstraction levels, including the system, register-transfer, logic, circuit, transistor and process levels. To address this critical area through a common forum, the IEEE Transactions on VLSI Systems have been founded. The editorial board, consisting of international experts, invites original papers which emphasize and merit the novel systems integration aspects of microelectronic systems including interactions among systems design and partitioning, logic and memory design, digital and analog circuit design, layout synthesis, CAD tools, chips and wafer fabrication, testing and packaging, and systems level qualification. Thus, the coverage of these Transactions will focus on VLSI/ULSI microelectronic systems integration.
