Abstract :
In this paper, we show that it is possible to use built-in-self-test circuitry to correct some errors of the ADC under test. We take the example of the LH-BIST architecture we have previously developed to measure the ADC offset value. The interest of LH-BIST architecture is that one of its registers is directly connected to the output of the convert. Hence, this register can be use to digitally modify the running code of ADC according to offset value extract by this very LH-BIST circuitry.
