Abstract: The present disclosure relates in general to devices, systems and methods for wireless communication, and in particular to communication using a proximity integrated circuit card (PICC). Example embodiments include a circuit (100) for a PICC, the circuit comprising an input stage (101), a decoding module (106) and a bias adjustment module (117), the bias adjustment module (117) configured to receive an output code from the decoding module and provide a bias adjustment signal to the input stage (101), the bias adjustment module (117) configured to iteratively tune the bias adjustment signal based on a measurement of the output code, with successive steps tuning the bias adjustment signal by a smaller amount until the output code is within a decoding range.
