Design of Continuous-Time Σ∆ Modulators with Real Analog Blocks
نویسندگان
چکیده
The design of Continuous-Time (CT) Sigma-Delta modulator obtained by a discrete-time prototype is discussed. A proper heuristic transformation of the prototype enables an exact equivalence of CT and DT. This permits the trimming by computer simulations of the coefficients of the CT to account for the effect of real analog blocks. Simulation results for a second and third order scheme with real DACs verify the proposed methodology.

Time-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 کاملBehavioral modeling of continuous time ∆Σ modulators
A mixed-signal continuous time behavioral model of a continuous time delta-sigma modulator (CT ∆Σ) is presented. CT ∆Σ modulators, by their nature, are mixed-signal systems. That fact creates a discontinuity in the traditional IC design flow which assumes that “discrete” and “continuous” time domain designs require separate design tools. In this work, we present a top level behavioral CT ∆Σ mod...

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...
