Patent ID: 8500030

Claim:
An electronic circuit adapted for connection to an antenna to form a responder that operates without resetting to zero when a power supply of the electronic circuit is switched on, the electronic circuit comprising: (a) first and second contact pads respectively adapted for connection with first and second ends of the antenna; (b) a first extractor of a first clock signal electrically connected to the first contact pad; (c) a logic circuit associated with a memory; (d) a second extractor of a second clock signal electrically connected to the second contact pad; and (e) a generator of a zero reset signal of the logic circuit connected as input to the first and second extractors, wherein the generator is configured to supply the zero reset signal to the logic circuit as soon as a difference between a number of pulses of the first clock signal and a number of pulses of the second clock signal is equal to or greater than a predefined positive integer.
