Analog Diablog is the place to comment on the articles found in Analog Dialogue (or those that you'd like to see). It can also be used as a discussion forum on products, applications, technology, and techniques for analog, digital, and mixed-signal processing using Analog Devices components.
As low-power, handheld devices become more prevalent, printed circuit boards with a mixture of 5-V, 3.3-V, 2.5-V, and 1.8-V devices have become common, making the design of a JTAG chain challenging. The designer must determine both the operating voltage and the order to place devices that operate at different voltages. This article provides some tips and techniques for making a robust design.
The principal factors that affect data acquisition systems are: speed, accuracy, power dissipation, package size, and component cost, with varying factors becoming critical depending upon the application. A single op amp can be used to drive the ADC in an 8-channel data- acquisition system, reducing the cost and size of the overall system.
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.
