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

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.
