Large-Signal DG-MOSFET Modelling for RFID Rectification

This paper analyses the undoped DG-MOSFETs capability for the operation of rectifiers for RFIDs and Wireless Power Transmission (WPT) at microwave frequencies.For this purpose, a large-signal compact Blender model has been developed and implemented in Verilog-A.The model has been numerically validated with a device simulator (Sentaurus).It is found that the number of stages to achieve the optimal rectifier performance is inferior to that required Physical Therapy And Pain Management with conventional MOSFETs.In addition, the DC output voltage could be incremented with the use of appropriate mid-gap metals for the gate, as TiN.

Minor impact of short channel effects (SCEs) on rectification is also pointed out.
