By Rick Nelson, Editor-in-Chief -- EDN, 12/22/2009Berkeley Design Automation Inc has announced AFS RF (Analog FastSpice radio frequency), which Chief Operating Officer Paul Estrada calls the industry’s first true Spice-accurate noise-analysis tool for RF circuits. AFS RF accurately analyzes nanometer-scale device noise impact for all types of prelayout and postlayout circuits, ensuring early insight into its impact on performance, power, and area.
Before the emergence of AFS RF, designers had to use limited-spectrum RF tools that can only approximate device noise impact on RF circuits, Estrada explains. Such approximations are increasingly inaccurate with decreasing process geometries, often becoming grossly inaccurate in nanometer-scale circuits. Circuits with sharp transitions, such as switched-capacitor filters, charge pumps, and dividers; high-frequency circuits, such as RF front-end blocks; and oscillators are especially sensitive to these inaccuracies. Without accurate analysis, designers must include expensive design margin or risk missing specifications in silicon.
Using the industry’s first full-spectrum device-noise-analysis engine, Analog FastSpice RF provides true Spice accuracy for every run. For complex circuits, it is five to 10 times faster than traditional RF tools that can only approximate device-noise effects. AFS RF features the DNA (device noise-analysis) Advisor to characterize DNA requirements, high-capacity periodic-steady-state analysis for greater than 100,000-element postlayout circuits, full-spectrum periodic-noise analysis with true Spice accuracy, full-spectrum total oscillator-device-noise analysis capability with phase and amplitude noise, and harmonic balance for fast single-tone analysis of moderately nonlinear circuits.

This year the conference will be organized in Wroclaw, one of the oldest and most beautiful cities in Poland. It is located in southwestern Poland, 160 km from Germany and 120 km from the Czech Republic. It is well equipped with communication facilities: international airport, railways and highways, so is quite easy to get there.
As in previous years the papers should be prepared following the paper formatting requirements, however the format may be corrected till the final paper versions deadline (May 15th, 2010). The paper registration and updates should be proceeded by your personal account at the conference web page after log on.
With further questions please contact Dr. Mariusz Orlikowski, the MIXDES 2010 Conference Secretary.

Advances in manufacturing technologies of CMOS integrated circuits have enabled obtaining the shrinkage of the device dimensions together with higher working frequencies at the expense of a greater dispersion in their characteristics. The impact of process variations specially affects the performance specifications of the analog and RF sections.
The main objective of this project is to develop design methods that allow to construct inherently robust circuits against manufacturing process variations. We intend to approach the problem from previous results already obtained by our group in predictive test. This test strategy consists in estimating the circuit performance parameters from indirect measurements, an approach easier to implement than by means of the standard methods.
The proposed solution consists, first, in implementing the elements to carry out the test process on the own chip; this is the well-known Built in Self Test technique. Then, the results of the predictive test are used to modify, either the value of a circuit element or the own structure of the circuit, with the aim of optimizing some of their performance specifications. Hence, self-adjustable or reconfigurable circuits are obtained.
Although the concept can be applied to any anlog circuit, its implementation has to be tailored for each kind of circuits. Initially it will be applied to two circuits: a low pass filter for a RF receiver (self-tuning) and a pipeline analog to digital converter (reconfiguration). Nevertheless, all through the project we will seek new objective circuits.
