Abstract :
Simple and low cost method based on Built-in-Tuning (BIT) of passive filters in RFIC transceiver is presented, which is used to compensate for variability induced imperfections in RF subsystems. Auto-calibration of filter resistance values, based on Design-Of-Experiment (DOE) methodology, is proposed. This approach investigates process and temperature monitoring of the frequency band, the image-rejection-ratio (IRR) and the I/Q-accuracy resulting to robust and low-cost solutions in multistandard wireless transceiver.
