Abstract: An apparatus, such as a radar system that conducts beamforming operations, includes a plurality of analog-to-digital-converters (ADCs) and an error correction system coupled to the ADCs. Based upon an assessment of a plurality of errors associated with the ADCs by the error correction system, the error correction system programs sampling operations for the ADCs. The error correction system includes an error correction unit that identifies the plurality of errors associated with a plurality of sub-ADCs of the ADCs, a selection unit coupled to the error correction unit that sorts the errors associated with the plurality of sub-ADCs, and a programming unit coupled to the selection unit that reconfigures the sorted errors to generate a sequence of sampling operations for the plurality of sub-ADCs.

Abstract: A wireless transceiver system includes a transmitter and a receiver. The transmitter includes a digital processor and a self-correction modulator coupled to the digital processor, wherein based upon a calibration correction assessment of an in-phase (I) signal and a quadrature (Q) signal received from the digital processor, the self-correction modulator generates a calibrated modulated signal. The self-correction modulator includes a core modulator and a calibration correction unit. The calibration correction unit is configured to correct an output of the core modulator based upon the calibration correction assessment. The calibration correction unit includes a calibration processing unit and a calibration modulator, wherein the calibration processing unit provides correction quantities that are used to program the calibration modulator to provide the self-corrected modulated signal.
