Abstract:
A contactless card is powered by an antenna connected to the input of a rectifier. An output of the rectifier is coupled to a processing unit that consumes a first current output from the rectifier. A current regulation circuit is connected to the output of the rectifier. The current regulation circuit operates to absorb a second current from the output of the rectifier such that a sum of the first and second currents is a constant current.
