Solutions for nonlinear characterization of high-power amplifiers Design How-To 12/6/2010 4 comments High-power RF amplifiers are used in telecommunications, biomedical, and military systems. With output power levels ranging up to 1 kW, these amplifiers are typically designed to operate near or into compression in order to provide the maximum output power possible. Designing high-power amplifiers requires a detailed analysis of its nonlinear behavior.
Two different ways of looking at noise figure Design How-To 12/6/2010 3 comments Reducing receiver-contributed noise may be the least expensive route to take but may also be the most challenging for the designer who must develop a low-noise amplifier (LNA) at the front end of the receiver. For those designers, an accurate and repeatable method for measuring noise figure will be a necessity.
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
