    Abstract: A method of calibrating a thermometer-code SAR-A/D converter is provided. The thermometer-code SAR-A/D converter includes an Nbit-bit digital-to-analog converter (DAC) for outputting an Nbit-bit output code. The DAC includes a first subconverter having a plurality of NTh thermometer elements Tj and a second subconverter having a plurality of NBin binary-weighted elements. The Nbit output code is equal to the sum of NBitTh and NBitBin where NTh=2NBitTh and NBitBin is equal to NBin=NBitBin. The calibration method includes determining an Integral Non-Linearity error value (εR) of an Rth thermometer-code level of the thermometer elements. The method further includes reducing the highest of the error value εR to obtain a reduced error value, and generating the output code according to said reduced error.

    Abstract: The present disclosure relates to a method of self-calibration of a successive approximation register-analog-to-digital converter. The method includes measuring an error value for each thermometer element of a plurality of thermometer elements and determining a mean value of measured error values. The method also includes generating a thermometer scale where each level of the thermometer scale will be an incremental sum of each value of a first subset, and each further level of the thermometer scale will be a sum of all values of a second subset plus the incremental sum of the elements of the first subset in any order. In addition, the method includes generating the output code according to the thermometer scale.

    Abstract: A method for processing signals received by a plurality of receiving antennas in a radar system, for example for road safety, which emits sequences of chirp-modulated signals, wherein the received signals are mixed with local replicas of the transmitted signals so as to generate, for each receiving antenna, a sequence of detection signals. The detection signals are subjected to Fourier-transform processing and beam-forming processing for generating values of range, azimuth, and speed for at least one obstacle or “target” detected by the radar system. The method includes an acquisition process for yielding approximate values of range and azimuth of the obstacle, and a tracking process for yielding accurate range, azimuth and speed values of the obstacle itself.
