Abstract (en)
[origin: WO2009001251A1] An electronic device (102) for contactless transmission of data comprises an autotransformer (103). Thus, only a part of a voltage induced into the electronic device (102) may be used by an integrated circuit (104) of the electronic device (102) due to the use of an autotransformer (103). This smaller voltage influences a stronger modulation of the integrated circuit (104). This modulation itself may operate not only an active part 108 of the autotransformer (103), i.e. the portion the integrated circuit (104) is connected to, but the whole autotransformer (103).
