Abstract (en)
[origin: WO9938114A1] A portable data device (102) employs a single coil (106) for receiving both power and data from a terminal (101) and includes a power rectifier (205) and an ASK data receiver (215). A shunt regulator circuit (211) is coupled between the power rectifier (205) and the ASK data receiver (215) and is used to control a mode selector (203). The mode selector (203) is used for switching between a power extraction mode of operation and a data exchange mode of operation.
