چکیده

This paper presents a mixed equation-based and simulation-based design methodology for continuous-time Sigma-Delta modulators from high level specifications down to Layout. The calculation and scaling of the SigmaDelta coefficients as well as circuit sizing and layout generation are implemented in the same analog design environment CAIRO+. The design of a complete third order current-mode continuous-time Sigma-Delta modulator is taken as an example to show the effectiveness of the proposed design 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...

A New Method for the High-Level Synthesis of Continuous-Time Cascaded Σ∆ Modulators

ABSTRACT This paper presents an efficient method to design cascaded Σ∆ modulators implemented with continuous-time circuits. Instead of using a discrete-to-continuous time transformation, the proposed methodology is based on the direct synthesis of the whole cascaded architecture. This leads to more efficient topologies in terms of circuit complexity, power consumption and robustness with respe...

Behavioral 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...

Fixed-step Simulation of Continuous-Time Σ∆ Modulators

A methodology for the simulation of continuous time sigma-delta (Σ∆) converters is presented in this paper. This method permits the simulation of Σ∆ modulators employing continuous-time filters using a fixed-step algorithm. The analysis method is based on the discretization of a continuous-time model and using a discrete simulator, which is more efficient than an analog simulator. In our analys...

Multibit Continuous Time Σ∆ Modulators with a Reduced Number of Comparators

A drawback of continuous time Σ∆-modulators is their sensitivity to clock jitter. An appropriate way to counteract this is to use a multi bit feedback loop. This requires a high resolution multi bit quantizer. However, every extra bit in the quantizer doubles its complexity and power consumption. In this paper, a new Σ∆-modulator architecture is proposed. The implementation issues are discussed...
