Current techniques for modelling RF power amplifiers don't provide the dynamic range necessary to simulate their performance properly when used in the energy-saving envelope-tracking mode necessary to give LTE terminals a decent battery life.

Bridging the analog-digital divide is tough, particularly when it comes to verification. The two domains are marked by a host of differences with regard to tools, methodologies and the basic means of developing and testing designs. Analog engineers do most of their work by building and moving graphics while their digital counterparts do most of [...]

A greater proportion of the layout requires more precise extraction at the 32nm and 28nm process nodes, so rules-based extraction tools can no longer deliver the accuracy needed to confirm acceptable electrical performance. Given the nature of parasitic elements in analog and mixed-signal (AMS) system-on-chip designs, designers need a parasitic extraction tool that provides gate-level, [...]

Process design kit (PDK) standards are one area that could greatly help reduce the disproportionate time and effort required to realize the analog portion of a design. PDKs have existed for two decades and provide access to foundry-verified data files for such AMS design elements as parameterized layout cells (PCells). However, most have been constructed […]

Circuit noise problems can originate from a variety of sources. By carefully examining attributes of the offending noise you can identify it’s source, thereby making noise reduction solutions become more apparent. There are three subcategories of noise problems: device, conducted and radiated noise. If an active or passive device is the major noise contributor, you […]

The IEEE Council for EDA has opened its website at www.c-eda.org. Earlier this fall, the IEEE Council for Electronic Design Automation (CEDA) took on formal existence with the election of its first officers. Design consultant and one time DAC general chair Alfred Dunlop is its launch president. He sets out why this is a great […]
