AB  - In this paper, we propose a small-sized and high performance cascaded delta-sigma DAC (CDS-DAC) that uses an analog FIR filter including a second mismatch shaping functions. If multi-bit DAC was composed, the mismatch caused by variation of elements degrades the overall performance in analog part. We propose novel CDS-DAC having a second-order mismatch shaping function, which can be realized with several switches in analog part and a first order mismatch shaper in digital part in order to improve a performance degradation caused by the mismaches. The simulation result is obtained the SNR of the proposed CDS-DAC is 122 dB when the oversampling ratio is 128 and mismatch of components is 1%.
