Abstract: A method for decoding a data stream carried by a modulated signal (SIG), said signal being modulated according to one protocol belonging to the group including protocols A and B of ISO/IEC14443 standard and protocol F of JIS.X.6319 standard, comprising:
receiving said modulated signal (SIG), detecting said protocol and decoding said data stream in accordance with said protocol using a clock signal (CLK), wherein, whatever the detected protocol, said clock signal (CLK) is a clock signal extracted from said received modulated signal (SIG).

Abstract: 1. An integrated circuit having an input configured to receive an induced signal (SIG), said induced signal (SIG) being modulated according to a protocol belonging to the group including protocols using ASK modulation and protocols using OOK modulation, said integrated circuit comprising:
- detection means (DET) configured to detect said modulation;
- decoding means (DEC) configured to detect said protocol.
- a configurable limiter (LIM) configured to limit the level of the induced signal and having a first configuration (MODE1) adapted to protocols using ASK modulation and a second configuration (MODE2) adapted to protocols using OOK modulation;
- control means (CM) configured to set the limiter in said first configuration (MODE1) until protocol is detected, and configured to switch the limiter from said first configuration (MODE1) to said second configuration (MODE2) if a protocol using OOK modulation is detected.
