Current Feature Articles Volume 42 — May 2008 Understanding Hot-Swap Controllers: Hot-Swap Circuit Design Example High-availability systems, such as servers, network switches, redundant-array-of-independent-disk (RAID) storage, and other forms of communications infrastructure must be designed for near-zero downtime throughout their useful life. Components that fail or need updating must be replaced without interrupting the rest of the system. This process, known as hot-swapping or hot-plugging, requires a hot-swap controller. Discrete- and Integrated Control of Power Amplifiers in Base Stations In wireless base stations, the power amplifier dominates the performance in terms of power dissipation, linearity, efficiency, and cost. Monitoring and controlling the PA makes it possible to maximize the output power while achieving optimum linearity and efficiency. This article discusses the elements of a monitoring-and-control solution for the PA using discrete components—and describes an integrated solution. Cooking Inductively: ADI iCoupler Technology Isolates Hob and User Interface Easy-to-use inductive cooking surfaces (hobs) are significantly safer, without flames or other direct heat sources on the hob. They have better overall performance, including faster heating time, and are gaining acceptance by consumers as they are becoming more affordable. Designing the circuitry that drives the inductive plate to heat metal pots requires an understanding of a wide variety of physical principles and techniques. Copyright 1995- Analog Devices, Inc.

The Back Burner AC Shield Enhances Remote Capacitive Sensing The principle of a user touch causing a capacitance change to activate a switch is well understood, but implementing a PCB sensor design with proper shielding and routing poses a challenge. Analog Devices provide a complete capacitive-sensing solution, including controller, evaluation tools, sensor design libraries, and software for the host microcontroller. Inexpensive High-Speed Amplifiers Make Flexible Clock Buffers Consumer electronics, which tends to be lower frequency and less demanding than typical clock buffering applications, can use inexpensive high-speed op amps as an alternative to traditional clock buffers. High-speed amplifiers are less expensive than traditional clock buffers, yet can accommodate a wide range of designs. |
