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 model has been developed and implemented in Verilog-A. The model has been numerically validated with a device simulator (Sentaurus). https://www.inmuebleslasmercedes.com/product-category/thermometer-probe-wipes/
