Various embodiments of the present disclosure disclose decoding techniques for mitigating data corruption due to duty cycle distortion, jitter, and other distortions to a digital signal. Decoding processes, apparatuses, and systems are provided that utilize a decoding framework for improving the accuracy of output bit streams generated from digital signals. An example process receives data indicative of a digital signal, generates a signal measurement for the digital signal that includes signal length descriptive between a two rising edges of a digital signal or two falling edges of the demodulated digital signal, and generates at least one portion of an output bit stream for the digital signal based at least in part on the signal measurement.

Decoding systems and methods for mitigating distortions in digital signals

A method for decoding a data stream carried by a modulated signal includes receiving the modulated signal. The modulated signal is modulated according to a protocol belonging to a group of protocols including at least three protocols. The method further includes extracting a clock signal from the received modulated signal, detecting the protocol, and decoding the data stream according to the detected protocol using the extracted clock signal.

Integrated circuits and methods for protocol detection and decoding in near field communications

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.

Method for limiting the level of a modulated signal received by a tag and corresponding limiter

An RFID transponder (T) suitable for communication with a reading device (RD) and adapted to be connected to a monitored unit (MU) is provided. The RFID transponder (T) comprises a comparing unit (CU) adapted to and arranged to receive a status signal from the monitored unit (MU) and configured to compare a value of the status signal to at least one predefined reference value and a state machine circuit (STM) connected to the comparing unit (CU) and configured to determine, based on a result of the comparison, whether the value of the status signal lies outside a range of operation defined by the at least one reference value. The state machine circuit (STM) is further configured to indicate the reading device (RD) that the value of the status signal lies outside the range of operation if the value of the status signal lies outside the range of operation.

In an embodiment, a carrier signal generation circuit can be used for a Radio-frequency identification (RFID) transponder device. A frequency divider circuit has a first input to receive a first frequency signal, a second input to receive a division ratio signal, and an output to provide a carrier signal as a function of the first frequency signal and the division ratio signal. A phase difference circuit has a first input to receive an analog reader device carrier signal, a second input to receive a signal based on the first frequency signal and an output to provide a digital phase difference signal as a function of the reader device carrier signal and the signal based on the first frequency signal. A signal processor has an input coupled to the output of the phase difference circuit.
