| 摘要 |
The invention relates to a contactless integrated circuit which receives a radio frequency signal. According to the invention, the circuit comprises a clock generator, said generator being used to produce a clock signal (CLK) from a first alternation (AC0) and a second alternation (AC1) which are representative of the radio frequency signal received. The invention also relates to a method of generating a clock signal, during which the first and the second alternations are compared in order to produce the clock signal. The invention is suitable for contactless cards, transponders, etc.
