Latest Patents
Peter D Capofreddi holds a patent for an "Efficient architecture for correcting component mismatches and circuit." This innovative error correction technique addresses both component mismatch and circuit nonlinearity errors. It utilizes look-up tables to store mismatch coefficients, which represent the errors introduced by component mismatch, as well as a series of offset and gain coefficients. These coefficients are used to form a piecewise-linear representation of the error introduced by circuit nonlinearities. The independent gain and offset parameters for each segment of the piecewise-linear representation allow for the accommodation of discontinuous functions. This leads to a more efficient implementation, as it enables the error introduced by mismatch in the components representing the most significant bits to be included in the piecewise linear table, while separate lookup tables are used for the less significant bits.
