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 […]
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 […]
Wafer-based Tunneling Magnetoresistive analog sensor targets fluid measurement apps
Coto Technology has released the new RedRock RR110 wafer-based TMR (Tunneling Magnetoresistive) analog sensor. Offering strong magnetic sensitivity, high directionality, small package size, and a highly-competitive price, the RR110 analog sensor is ideally suited for continuous fluid measurement applications including countertop appliances, white goods, utility meters, medical devices, security and anti-tampering applications, industrial positioning, and […]
Dual differential amp/ADC driver delivers 10 GHz gain-bandwidth with 1.1nV/√Hz noise
Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC6419, a dual 10GHz gain bandwidth product differential amplifier with very low input voltage noise density of 1.1nV/√Hz, delivering outstanding SNR performance for wideband signal amplification. Additionally, the LTC6419 offers low distortion, providing 85dB spurious-free dynamic range (SFDR) at 100MHz while driving 2VP-P signals. […]
How should grounds and commons be connected to each other?
We have already looked briefly at Earth ground (if any), chassis ground, and commons (often misnamed as “grounds”). These do not exist as unrelated connections in a system. The issues related to connecting commons and ground is the subject of countless articles, academic papers, vendor application notes, anecdotes, and even books. There are many rules […]
Ultra-low power accelerometer for IoT asset-health monitoring
Analog Devices, Inc. announced a next-generation accelerometer designed for long-period monitoring of the physical condition of high-value assets. With its extremely low power capabilities, the ADXL372 micropower high-g MEMS accelerometer targets Internet of Things (IoT) solutions where shock and impact on a unit during storage, transit, or use would adversely affect its function, safety, or […]
What are some specialized op amp variations?
The operation amplifier – commonly called the op amp – is the key building block of analog circuits. In its basic configuration, it is most often used to amplify a signal, of course. It can also be configured to perform mathematical operations such as implementing multiplication or division of two signals, take a square root, […]
Ultra-broadband amplifiers have output power of tube amplifiers in compact, solid-state modules
Qorvo has introduced three new solid-state power amplifier (SSPA) modules that further expand the power and frequency range of the company’s Spatium® amplifier family. The modules are optimized for electronic warfare applications, enabling defense customers to use ultra-wideband SSPA technology as an alternative to traveling wave tube amplifiers (TWTAs). “The need for wider bandwidth, higher frequency […]
Working with op amps: tying down floating pins
Operational amplifiers are used in many configurations and with many variations on specifications, depending upon the application. However, an IC package of operational amplifiers will often come with several in a package (e.g., a “quad pack” will have four op amps). If you have leftover, unused op amps on the same chip, the unused ones […]
