Abstract [en]

For small integrated CMOS digital chips that communicate via analog signals the size and the cost of the AD-converters is a problem. An integrated CMOS AD-converter that could be built into the chip would solve this problem. In a CMOS process, the manufacturers only guarantee a very low accuracy of the resistances. The components of the ADC are therefore very inaccurate. The purpose here is to present a method for identification of the errors in the ADC. The algorithm works while the ADC is used and it does not assume any knowledge of the input signal except that the distribution function is smooth. The estimated values can then be used in the chip to compensate for the errors in the ADC. The algorithm is evaluated on simulated data.
