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...
This paper presents a built-in tuning technique in radiofrequency receivers using on-chip polyphase filters. Auto-calibration of the 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 in robust and low-cost solutions.
This paper presents a built-in tuning technique of local oscillator part of radiofrequency (RF) transceiver using on-chip temperature sensor and process monitoring in order to cancel the process, voltage and temperature (PVT) drift of the modulating frequency. An auto-calibration of the VCO, based on Design-Of-Experiment (DOE) methodology, is proposed. This approach investigates process and temperature...
