A Reuse-based framework for the design of analog and mixed-signal ICs
(The International Society for Optical Engineering -SPIE, 2005)
Despite the spectacular breakthroughs of the semiconductor industry, the ability to design integrated circuits (ICs) under stringent time-to-market (TTM) requirements is lagging behind integration capacity, so far keeping ...

Geometrically-constrained, parasitic-aware synthesis of analog ICs
(The International Society for Optical Engineering - SPIE, 2005)
In order to speed up the design process of analog ICs, iterations between different design stages should be avoided as much as possible. More specifically, spins between electrical and physical synthesis should be reduced ...

Accurate VHDL-based simulation of Sigma Delta modulators
(Institute of Electrical and Electronics Engineers, 2003)
The computational cost of transient simulation of /spl Sigma//spl Delta/ modulators (/spl Sigma//spl Delta/Ms) at the electrical level is prohibitively high. Behavioral simulation techniques offer a promising solution to ...

Continuous-time cascaded ΣΔ modulators for VDSL: A comparative study
(The International Society for Optical Engineering - SPIE, 2005)
This paper describes new cascaded continuous-time ΣΔ modulators intended to cope with very high-rate digital subscriber line specifications, i.e 12-bit resolution within a 20-MHz signal bandwidth. These modulators have ...

Effect of Clock Jitter Error on the Performance Degradation of Multi-bit Continuous-Time ΣΔ Modulators With NRZ DAC
(2005)
This paper analyses the effect of the clock jitter error in multi-bit continuous-time ΣΔ modulators with non-return-to-zero feedback waveform. Derived expressions show that the jitter-induced noise power can be separated ...

MATLAB/SIMULINK-Based High-Level Synthesis of Discrete-Time and Continuous-Time Sigma-Delta Modulators
(Institute of Electrical and Electronics Engineers, 2004)
This paper describes a tool that combines an accurate SIMULINK-based time-domain behavioural simulator with a statistical optimizer for the automated high-level synthesis of ΣΔ Modulators (ΣΔMs). The combination of high ...

On the suitability and development of layout templates for analog layout reuse and layout-aware synthesis
(The International Society for Optical Engineering - SPIE, 2005)
Accelerating the synthesis of increasingly complex analog integrated circuits is key to bridge the widening gap between what we can integrate and what we can design while meeting ever-tightening time-to-market constraints. ...
