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,
