Under the Hood of the Kyocera K112: Low-tier phone leans on analog Teardown 2/16/2005 Post a comment First launched in Brazil, the K112 handset includes games, calculator, ringtones, and an alarm. On a more technical note, the handset also features an internal antenna— an amazing bit of RF engineering in itself—to bypass those breakage-prone stubs and whips. From the February Planet Analog magazine folio, Portelligent's David Carey was impressed.
MOSFET or bipolar, which should you use? Design How-To 2/9/2005 Post a comment MOSFET or bipolar, which should you use? Recent developments in bipolar transistors position the technology to rival or exceed MOSFET performance in many applications. From powermanagementdesignline.com, a Zetex engineer reviews the characteristics and benefits of each technology to extract the best system performance.
Application processors duel Teardown 2/7/2005 Post a comment Convergence of functionality in handset designs is constantly raising the bar for value-added features, such as cameras, games, music playback and video capturing. It is estimated that the average cost of a handset will drop from about $125 today to $110 by 2008. In contrast, the average cost of the ICs within the handset will increase from approximately $40 today to $44.50 by 2008, as consumers demand higher functionality at a low price. A versatile application processor is key to achieving a s
Drones are, in essence, flying autonomous vehicles. Pros & cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight, as are piloted airplanes? Is the technology advancing faster than we can answer the questions it poses?
