As part of a new series of high-speed analog-to-digital converters (A/D converters), Analog Devices, Inc. (ADI) today introduced the AD9208. Engineered for gigahertz-bandwidth applications, this A/D converter meets the increased spectral efficiency demands of 4G/5G multi-band wireless communications base stations. It also meets the reduced run-time targets of multi-standard production instrumentation and provides greater detection […]

Passive sensors and active sensors: What are they?
“Passives” in general within the electronics community are devices that do not drive or transmit power or signals. Passive Sensors do not control electricity directly and do not require external power sources to accomplish control of an electrical signal. Examples of passive components are resistors (R), capacitors (C), inductors (L), transformers, antennas, potentiometers (variable resistors), […]
Low-light image sensors work at near-infrared wavelengths
ON Semiconductor is expanding its portfolio of Interline Transfer Electron Multiplication CCD (IT-EMCCD) image sensors with new options that target not only low-light industrial applications such as medical and scientific imaging, but also commercial and military applications for high-end surveillance. The new 4 megapixel KAE-04471 uses larger 7.4 micron pixels than those found in existing […]
Pulse Width Modulation (PWM): what is it and how does it work?
Digital signals have two positions: on or off, interpreted in shorthand as 1 or 0. Analog signals, on the other hand, can be on, off, half-way, two-thirds the way to on, and an infinite number of positions between 0 and 1 either approaching 1 or descending down to zero. The two are handled very differently […]
What is a clock and what are its critical parameters (Part 2)?
The performance of a clock function, which includes the crystal and associated circuitry, is defined by parameters which are measured over both the short term and long term. It is also characterized by change in specifications due to temperature variations, aging, and mechanical considerations such as vibration and shock. How is clock performance defined? Both […]
Top analog threads on EDAboard.com – March
(editor’s note: Intrigued by the problem? Have a question or another solution? Then click the “Read more” link and follow the conversation on EDAboard.com or log in to EDAboard and participate in the analog IC forum threads.) Battery voltage warning – I have 2 circuits. The idea is to show a warning when the battery drops […]
Analog Devices expands cable infrastructure solutions with acquisition of broadband GaAs and GaN amplifier expert OneTree Microdevices
Analog Devices, Inc. announced the acquisition of OneTree Microdevices, Inc., a privately held company based in Santa Rosa, California. ADI is a leading supplier of mixed-signal solutions for cable access ranging from data converters through clocking and control/power conditioning. With the acquisition of OneTree Microdevices’ GaAs and GaN amplifier portfolio, which offers best-in-class linearity, output […]
What is a clock and what are its critical parameters (Part 1)?
The “clock” function is a standard part of nearly every electronic system, with very few exceptions. Behind this simple-sounding, commonplace word, there is an array of complexity and subtlety in definition, performance, and design. Clocks are both vital and ubiquitous, so it is worth understanding the different functions they fulfill, they ways they can be […]
64 Gbaud linear modulator drivers enable next-gen CFP2-ACO and DCO modules
MACOM Technology Solutions Inc. announced the MAOM-00641X series of three surface mount 64 Gbaud linear modulator drivers to enable the next generation of high capacity coherent transmission systems. Leveraging existing fiber installations, today’s service providers are challenged to maximize their bandwidth and increase their data throughput-per-fiber. By maximizing the data rate on a single wavelength, operators […]
