Design of a high speed 3rd order sigma-delta modulator
초록
An efficient technique to trade off speed for resolution is the sigma-delta modulation (SDM). This paper proposes a new SDM architecture to improve conversion rates and SNR(Signal-to Noise Ratio) by using master clock and four divided clock. The charateristics of the proposed SDM are simulated in MATLAB environment. and optimizing the capacitor sizes is done by iterative processing. other analog characteristics are simulated using 0.65
