Histogram Based Correction of Matching Errors in Subranged ADC

• A method for correcting matching errors in an ADC is presented. The method uses the unknown input data from the application and does not require any test signal. Two algorithms for implementing the method are compared. One algorithm is general and works on any type of ADC. The other algorithm utilizes the subranged architecture of a specific ADC and is very simple to implement in hardware. The signal quality is similar for both algorithms.
