Abstract
A background method for precise mismatch detection is proposed. This technique uses a correlation between selection-codes and the output of DAC, which corrects all element errors in the internal DAC of a pipelined ADC. The proposed mismatch detection method realizes background mismatch detection without interrupting conversion sequence and reduces an effect of quantization errors. Simulation results applying the proposed method to the 14-bits pipelined ADC show 19dB SNDR and 23dB THD improvement
