Nyquist criterion based design of continuous time Σ∆ modulators

چکیده
In this paper we propose a way to design continuous time Σ∆ modulators. The method is based on the Nyquist stability criterion. Based on this criterion we propose to use the vector gain margin as a robust stability margin. Using this margin as a design criterion we design a robustly stable modulator. Finally, we also show how this margin can be used to evaluate the relative stability of a designed modulator.

The Nyquist Criterion: A Useful Tool for the Robust Design of Continuous-Time Σ∆ Modulators
In this paper we introduce a figure of merit for the robustness of continuous-time Σ∆ modulators. It is based on the Nyquist criterion for the equivalent discrete-time (DT) loop filter. We show how continuous-time modulators can be designed by optimizing this figure of merit. This way we obtain modulators with increased robustness against variations in the noise-transfer-function (NTF) paramete...
متن کاملTime-Mode Signal Quantization for Use in Sigma-Delta Modulators
The rapid scaling in modern CMOS technology has motivated the researchers to design new analog-to-digital converter (ADC) architectures that can properly work in lower supply voltage. An exchanging the data quantization procedure from the amplitude to the time domain, can be a promising alternative well adapt with the technology scaling. This paper is going to review the recent development in t...
متن کاملA Rigorous Approach to the Robust Design of Continuous-Time Sigma-Delta Modulators
In this paper we present a framework for robust design of continuous-time Σ∆ modulators. The approach allows to find a modulator which maintains its performance (stability, guaranteed peak SNR, . . . ) over all the foreseen parasitic effects, provided it exists. For this purpose, we have introduced the S-figure as a criterion for the robustness of a continuous-time Σ∆ modulator. This figure, in...
متن کاملNyquist-criterion based design of a CT ΣΔ-ADC with a reduced number of comparators
In this paper we present a prototype continuous time Σ∆-modulator in a 0.35 μm technology. The circuit has a 6-bit internal quantizer. Through the combination of a modified architecture and comparator interpolation this high quantizer resolution is achieved with only 15 comparators. However, it turns out that this approach imposes a severe speed constraint on the analog adder circuit. The modul...
متن کاملDesign of Continuous-Time Σ∆ Modulators with Sine-Shaped Feedback DACs
This work presents a general method to design continuous-time Σ∆ modulators with sine-shaped feedback DACs. A discrete time to continuous time transformation technique is used to compute the continuous-time loop filter coefficients, taking into account the sinusoidal feedback. Examples of high order lowpass and bandpass continuous-time Σ∆ modulators are given as an illustration for the proposed...
