    摘要: An integrated circuit, includes: an input configured to receive an induced signal that is modulated according to a protocol belonging to the group including protocols using ASK modulation and protocols using OOK modulation; a detection circuit configured to detect the modulation of the induced signal; a decoding circuit configured to detect the protocol; a configurable limiter configured to limit a level of the induced signal and having a first configuration adapted to protocols using ASK modulation and a second configuration adapted to protocols using OOK modulation; and a control circuit configured to set the limiter in the first configuration until a protocol is detected, and to switch the limiter from the first configuration to the second configuration in response to a protocol using OOK modulation being detected.
