摘要: This paper presents a means to overcome the high sensitivity of continuous-time sigma-delta (/spl Sigma//spl Delta/) modulators clock jitter by using modified switched-capacitor structure with resistive element in feedback digital-analog converter (DAC). The reduced is both simulated and proven measured results from two implemented third-order modulators. Additionally, nonideal behavior analyzed analytically simulations.
