Abstract: 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.

Abstract: 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.
