N2 - The analysis and simulation of a novel approach to achieve Capacitive Digital-to-Analog Converter (CDAC) mismatch error shaping using the traditional Data Weighted Averaging (DWA) algorithm is presented. The approach includes dissociating the ADC/DAC processes when extracting the quantization error in a Noise Shaping Successive Approximation Register (NS SAR) architecture. The proposed idea is implemented and validated with behavioral simulations in Matlab®-Simulink® of a 10-bit 3rd order NS SAR ADC, showing a first-order mismatch error shaping in the presence of CDAC mismatch.
