Earning calls sure are interesting! Below is an excerpt from the TSMC Q209 call (transcript from seekingalpha). The discussion revolves around the 40nm yield issues and TSMC's ramp to improving the yield. Dr. Liu really hits on a key element of DFM...(read more)

Hi,

I am designing a resistive feedback TIA which needs a capacitor in its feedback loop for stability.

I would like to know the effect of a feedback capacitor on the phase margin to determine the optimal capacitance value.

My plan is to add it to the results after the stb analysis by using the direct plot>main form > phase margin (add to outputs).However it not getting added to my results list.

What could be a problem? Is there a way to add phase margin to the results using the calculator? 

I also find that the gain from the stability analysis(the closed loop gain) is different from that of the gain obtained for the closed loop simulation in AC analysis. Why is the difference, how is it computed in stability analysis?

Thanks,

-Rakesh.

Izlebizi Video Script remote add administrator account exploit.

A Win32 tool for easing/automating the process of creating IDS/IPS signatures for SMTP based worms, providing a comfortable GUI, including raw base64 variants and Snort signatures support. This tarball is the binary executable version.

This Metasploit module exploits a format string vulnerability in the LPRng print server. This vulnerability was discovered by Chris Evans. There was a publicly circulating worm targeting this vulnerability, which prompted RedHat to pull their 7.0 release. They consequently re-released it as "7.0-respin".

A vulnerability is present in AT&T TCP/IP Release 4.0 running on SVR4 systems for both the 386/486 and 3B2 RISC platforms. The problem is in the remote execution server /usr/etc/rexecd and a new version of rexecd is available from AT&T.

Debian Security Advisory DSA 830-1 - Drew Parsons noticed that the post-installation script of ntlmaps, an NTLM authorization proxy server, changes the permissions of the configuration file to be world-readable. It contains the user name and password of the Windows NT system that ntlmaps connects to and, hence, leaks them to local users.

Yield-cos have been grabbing headlines lately. Typically, large utilities spin off their high-yield alternative energy operations into separate smaller companies called yield-cos. These new companies are then taken public to attract individual and institutional investors.

The U.K. Green Investment Bank is set to tie up the first investments in a $1.6 billion fund by the end of March, part of Britain’s push to cement its dominance in offshore wind power.

U.S. electricity markets face years of higher prices as clean-air regulations shut more coal-fired power plants than earlier forecast, cutting supply and forcing producers to rely more on natural gas.

Fossil fuels are reaping $550 billion a year in subsidies and holding back investment in cleaner forms of energy, the International Energy Agency said.

President Barack Obama will pledge $3 billion to a United Nations climate-change fund that’s intended to help poor nations boost renewable energy and counter the ill effects of global warming.

The news about the Environmental Protection Agency’s plan to limit carbon pollution from existing power plants just got even better: the proposed Clean Power Plan (CPP) can save the power industry and its customers — us — as much as $2 to $4 billion in 2020 and $6 to 9 billion in 2030, while cleaning our air and modernizing the electricity sector.

The siren call of 2020 corporate environmental sustainability goals is quickly getting louder, as corporate leaders realize they must go further today to achieve their sustainability targets for tomorrow. Increased use of renewable energy is an ambitious goal for some of the world’s largest companies, as 59 percent of the Fortune 100 and nearly two-thirds of the Global 100 have set GHG emissions reduction commitments, renewable energy commitments or both, according to a recent Ceres’ report, Power Forward: Why the World’s Largest Companies Are Investing in Renewable Energy. One global consumer products company, for example, plans to derive 30 percent of its energy from clean sources by 2020.

The U.S. Department of Commerce just announced that it will add high tariffs for solar modules imported from China. The Canadian government is also investigating the adoption of similar measures, following recent complaints filed by Ontario-based solar manufacturers. With the solar industry in hypergrowth, it’s not a surprise that these governments are interested in boosting new jobs, protecting their economies, and fostering the solar sector. The problem is that tariffs are a short-sighted approach that actually attack the future of North American solar on its home soil, and likely destroy more jobs than they create.

The online community of readers who visit RenewableEnergyWorld.com is an important aspect of the news and information that we offer renewable energy stakeholders. We often post news that we feel will get people to view important topics from new angles, offering insights and opinions about technology, policy and more. Often that leads to engaging and informative discussions that add even more value to the article that we have posted.

Serbia seeks to unblock investment in renewable energy after adopting legislation that opens gas and power markets in line with European Union guidelines.

In June, the U.S. Environmental Protection Agency (EPA) proposed a rule to restrict the amount of carbon dioxide released from power plants. The rule calls for reducing carbon 30 percent by 2030 over 2005 levels. Many have praised the aggressive proposal, while others are less favorable.

Clean energy investments in India increased to $7.9 billion last year and are expected to surpass $10 billion in 2015.

The Obama administration is proposing a $4 billion fund to reward states that exceed cuts in greenhouse-gas emissions, and wants Congress to back steeper royalty rates for oil, gas and coal extraction from public land.

The annual outlook issue of Renewable Energy World magazine is our attempt to predict what will happen within the renewable energy industry over the course of the year. To do this, we went straight to the top of major renewable energy companies, asking CEOs and presidents to tell us where they are devoting their company resources in order to capitalize on some of the market growth that they expect to see in 2015.

U.K. electricity from low-carbon sources accounted for almost a quarter of the country’s generation in the fourth quarter as Drax Group Plc converted a second coal-power plant to burn wood.

A "dark horse" is defined as a little-known entity that emerges to prominence in the face of competition — a contestant that seems unlikely to succeed. I borrow the term from a conversation last week, wherein India was referred to as the dark horse in the global race to go solar.

Brazil will increase the use of renewable energy, target zero net deforestation and push for low-carbon agriculture as part of its climate proposal, Environment Minister Izabella Teixeira said in an interview.
