  • Patent number: 8410960
    Abstract: A method is disclosed of compensating the output of an ADC for non-linearity in the response of the ADC. The method comprises converting an analog input signal to uncorrected digital ADC output samples, applying a vector of correction variables to each of a block of uncorrected ADC output samples to provide a block of corrected ADC samples, and iteratively minimizing a measure of the spectral flatness of the block of corrected ADC samples with response to the vector of correction variables.

  • Patent number: 8410787
    Abstract: An integrated circuit comprises a plurality of clock domains (10, 12). Test data is shifted into the integrated circuit through a scan chain (100, 14, 104). In a test mode a connection is interrupted between a functional output of a first clock domain (10) and a functional input of a second clock domain (12). Test data is applied from the scan chain (100, 14, 104) to the functional input and a test response is captured into from the functional output. A delay circuit (24, 28) is used to delay transfer of the test result from the scan cell (21) to the functional input when the test result is captured in the scan cell (21), to ensure that timing differences between the clock domains do not affect the test. Subsequently the test result is shifted through the scan chain.
