We were hosting/caching some DMOZ category pages here at GCEK Net. Since that is not adding any value, we are discontinuing the same.

Ideally, you will find what you are searching for by taking the part after QRY= on the URL you typed, and adding it to http://www.dmoz.org

Control Algorithm for Voltage Regulation

A Hybrid Control Algorithm for Voltage Regulation in DC–DC Boost Converter

Sreekumar, C. & Agarwal, V.

A new switching control algorithm based on state trajectory approximation is proposed to regulate the output voltage of a representative second-order DC-DC converter – the boost converter. The essence of the proposed algorithm is to trap the system into a stable limit cycle while ensuring the required voltage regulation. Unlike some of the earlier algorithms, the concept is applicable to both continuous and discontinuous current modes of operation, making it viable over a wide operating range under various load and line disturbances. A hybrid-automaton representation of the converter is used to perform the analysis, and the control problem is simplified to a guard-selection problem. Guard conditions, governing the transition of the converter operation from one discrete state to the other in a hybrid-automaton representation, are derived. The hybrid-automaton-based control system is implemented by using the state flow chart feature of MATLAB, and extensive simulations are carried out to check the suitability of the algorithm. The hybrid control law is also validated in real time by using a laboratory prototype. The experimental and simulation results prove the effectiveness of the proposed control law under varying line and load conditions.

We are aware that the member search functionality in GCEK Net is something that our alumni used very frequently. Unfortunately, that facility is not available at the moment as we are in the process of replacing it with a better system.

If you are an alumni and haven’t registered yet, please take time to do so. For all you know, your colleagues could be searching for your details too.

We have brought in certain sections like research papers as part of the current launch. Please browse through and leave your valuable comments.

We had discontinued this temporarily due to heavy traffic. Putting these downloads back in as a considerable amount of our visitors come here looking for these.

Analog IC Design – Training – NIT Calicut

Sajin — Thu, 12 Mar 2009 03:29:21 +0000

The Dept of Electronics & Communication,National Institute of Technology,Calicut, is planning to conduct an AICTE sponsored faculty development program. The area is ‘ANALOG IC DESIGN’ which is of great relevance today and is included in the curriculum of most of the universities.

The brochure and application form are attached herewith.

Error Localization of Complex DFT Codes

Error Localization of Complex DFT Codes Using Propagator Method

Nidhin Kizhakan

In this paper we consider the problem of error localization of complex DFT codes and the reconstruction of message. A propagator-based subspace algorithm is proposed for error localization of quantized DFT codes. The propagator method requires only linear operations and does not require any eigendecomposition of syndrome covariance matrix as in conventional subspace method such as MUSIC etc. The performance of the proposed method is compared with MUSIC algorithm. Simulation results show that the proposed method performs equal to the MUSIC algorithm with less computational complexity.

An Incremental Technology Database Structure for Analog/Mixed-Signal Methodologies

Sini Mukundan

OpenAccess plays a wide range of roles in the EDA world, including interoperability enabler, communication tool, and advanced platform for software providers to develop powerful, cutting-edge applications. It is a new, powerful flexible database which gives the design community a chance to revisit its most basic design infrastructure methodologies. Probably one of the most challenging features in this respect is the increased flexibility that OpenAccess 2.2 offers in technology creation and partitioning.

Sequential Equivalence Techniques for High Performance Design

Sini Balakrishnan

Quite often in semiconductor industry, when a product is nearing its launch date, most of us have had the deja-vu situation of performance to time-to-market trade-offs; especially in high-performance designs. Sequential equivalence checking opens up possibilities in this area, by enabling performance-tuning related sequential micro-architectural changes to be verified with significantly lower impact on effort estimates and risk. This nascent technology promises to change the way we look at eleventh hour changes.

Coming Back

Sajin — Thu, 11 Dec 2008 12:17:41 +0000

After a significant phase of disrupted service, we are getting back online. This time around, we are moving to standard platforms (rather than fully custom code) so that maintenance and upgradations are easier.

Hope you like it.
