Controller of the energy received by an antenna for preventing corruption of data during a write operation in non-volatile memory of a transponder

摘要

The circuit has an antenna for receiving radio frequency signals and an extraction unit for extracting a part of the energy necessary for the transponder circuit, non-volatile memory unit and a control logic unit. The control logic unit is arranged for performing a write operation. An evaluation unit (71) includes a resistive divider including a set of resistors or a programmable current source and rectifier unit on each connector of the antenna for simulating a write operation in the memory and the energy that is recuperated by the power supply.
