  • Novel UHF passive rectifier with tunnel FET devices 

    Nunes Cavalheiro, David Manuel; Moll Echeto, Francisco de Borja; Valtchev, Stanimir (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    The increase of the losses in UHF passive rectifiers with Tunnel FET devices at large RF AC amplitudes are mainly due to the high reverse current inherent of this technology when subjected to high reverse bias conditions. ...
