Jitter analysis of bandpass continuous-time ΣΔMs for different feedback DAC shapes
نویسندگان
چکیده
In this paper, a simple and intuitive technique for analyzing clock jitter effect on bandpass Continuous-Time SigmaDelta (Σ∆) modulators is introduced. The power spectral density of the jitter noise for different feedback DAC shapes are derived and compared. It is shown that DAC output signal shapes used to reduce clock jitter sensitivity in lowpass Continuous-Time Σ∆ modulators may not be suitable for bandpass modulators.

A generalized approach to design CT ΣΔMs based on FIR DAC
Abstract— In this paper, a generic and simple approach to design Continuous-Time Sigma-Delta Modulators (CT ƩΔMs) based on Finite Impulse Response Digital-to-Analog Converter (FIR DAC) is introduced. The numerical conversion from Continuous-Time to Discrete-Time allows the designer to explore complex modulator architectures and different feedback DAC shapes, without dealing with difficult equat...

This paper proposes a continuous-time bandpass ∆ΣAD modulator architecture which performs high-accuracy AD conversion of high frequency analog signals and can be used for next-generation radio systems. We use an RF DAC inside the modulator to enable subsampling and also to make the SNDR of the continuous-time modulator insensitive to DAC sampling clock jitter. We have confirmed that this is the...

متن کاملA triple-mode continuous-time sigma delta modulator with switched-capacitor feedback DAC for a GSM- EDGE/CDMA2000/UMTS Receiver
Time jitter in continuous-time 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 significantly. In this paper, an and continuous-time fifth-order modulator with 1-bit quantizer and SC feedba...
