A triple-mode continuous-time ΣΔ modulator with switched-capacitor feedback DAC for a GSM-EDGE/CDMA2000

A triple-mode continuous-time ΣΔ modulator with switched-capacitor feedback DAC for a GSM-EDGE/CDMA2000

Time jitter in continuous-time ΣΔ modulators is a known limitation on the maximum achievable signal-to-noise-ratio (SNR). Analysis of time jitter in this type of converter shows that a switched-capacitor (SC) feedback digital-to-analog converter (DAC) reduces the sensitivity to time jitter significa...
