CAMARILLO, CALIF. High-frequency multiplayer ceramic inductors for RF and wireless applications feature self-resonant frequencies up to 4 GHz and quality factors up to 55 at 800 MHz. The devices from Johanson Technology Inc. include three standard SMD chip sizes: 0402 with inductance values of 1.5 to 10 nH, 0603 (1.5 to 47 nH) and 0805 (1.5 to 100 nH). Price is 10 to 20 cents in quantities of 25,000.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
