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. Using, for example, a barrel shifter function, the sorted errors are reconfigured by the programming unit such that a summation of elements in each column in a matrix in which the sorted errors are stored are within a predefined value.
