Smart Metering Technology Promotes Energy Efficiency for a Greener World

We’re all familiar with the electricity meter in the garage or basement. We may even have looked at it once or twice to phone an up-to-date reading to the utility company in place of an estimate. Thanks to technology, a quiet revolution is taking place inside this innocuous looking meter. This article describes how automatic meter reading and the smart grid can help improve energy efficiency and reduce carbon emissions.

Analog Front End for Femto Base Stations Brings Wireless Connectivity Home

Imagine a device that can provide high-quality cellular reception within your home, allowing you and your family unlimited voice and data usage for a low monthly fee. A femto base station, usually referred to as a femtocell, provides all that and more. This small wireless device, which improves local wireless coverage when placed in a home or office, is poised to dramatically change the wireless infrastructure landscape.

Considering Multipliers, Part 1 [The Wit and Wisdom of Dr. Leif–7]

Multipliers exploiting translinear loops, current-mirrors, current conveyors, and linear gm cells continue to be indispensable more than sixty years since the very first fully monolithic ICs were fabricated in 1967. In this futuristic tale, Drs. Newton Leif and Niku Chen discuss multiplier topologies, uses, and history. Leif also provides some hints as to how neurons, which are translinear, behave exactly like bipolar junction transistors.

Low-Cost Video Multiplexing Using High-Speed Amplifiers

The large number of video sources connected to a single display makes video switching a requirement in home and automotive entertainment systems. In the home, the set-top box, DVR, VCR, DVD player, video game, and PC all feed one display. In cars, the rearview camera, DVD player, navigation system, and auxiliary devices all feed the display.

Equalization and Pre-Emphasis Enable Use of 30-m Cat-5 UTP Cable

The use of the category-5 unshielded twisted-pair cable has grown due to its respectable performance and low cost. Currently being used for keyboard-video-mouse networking, this type of cable provides an inexpensive solution for connecting HDTV components when long-distance connectivity is required.
