Title Integrated circuit comprising a clock-signal generator, smart
card comprising an integrated circuit of this kind and associated method for
the generation of clock signals
Abstract A contactless integrated circuit receiving an RF
signal comprises a clock-signal generator to produce a clock signal from a
first half wave and a second half wave representing the received RF signal.
Also disclosed is a method for the generation of a clock signal in which the
first half wave and the second half wave are compared to produce the clock
signal. The invention is adapated for use in contactless cards, transponders,
and the like.
