Dual-output, automotive-grade MEMS oscillators boost reliability, vibration resistance, and tolerance to shock
Technological advancements and the increased adoption of complex electronics systems in modern vehicles requires superior timing performance and reliability. Timing precision, accuracy and tolerance to harsh environments are essential to ensuring precise operation in today’s highly advanced automotive systems. Microchip Technology Inc. has unveiled the new DSA family of automotive-grade Micro-Electro-Mechanical Systems (MEMS) oscillators that […]
Factors to consider in purchasing a Solid State Drive (SSD) for computer storage
What factors should you take into account when you purchase an SSD? Keep in mind that the below are generalizations and that technology is improving all the time. Size matters. Before you buy, have an idea of how much data you would likely to the SSD in an average day. The average DVD movie is […]
Swivel-lid spring-pin BGA socket handles LP-DDR4 ICs
Ironwood Electronics recently introduced a new BGA socket addressing high-performance requirements for testing BGA devices — the SBT-BGA-7051. The contactor is a stamped spring pin with 31 gram actuation force per ball and cycle life of 125,000 insertions. The self inductance of the contactor is 0.88 nH, insertion loss < 1 dB at 15.7 GHz […]
Rotary encoders, Part 2: magnetic encoders
Part 1 of this FAQ looked at the optical rotary encoder, a low-cost, high-resolution, easy-to-use sensor for indicating incremental shaft position (although it can be “upgraded” to indicate absolute position as well). Q: What is the basic principle of the magnetic encoder? A: The magnetic encoder uses a rotating gear made of ferrous metal and […]
Signal-channel diversity and fading, Part 2: Frequency Diversity
In Part 1 we looked at space diversity, which is the simplest form of signal-channel diversity. It has been used with success since the earliest days of wires and wired links, and it sees new uses in 5G MIMO and other advanced RF systems. We next look at the other very common form of signal-channel […]
Fixed-energy wirewounds for high energy handling requirements
Stackpole’s WWP Series of wirewounds offers guaranteed pulse handling for high energy handling requirements. Standard wirewounds exhibit variable pulse handling due to materials flexibility and trimming processes. The WWP Series defines the element wire as robust as possible and does not require trimming. The result is a thru hole wirewound series with outstanding pulse handling […]
Analog vs Digital
I am principally an analog designer who also designs custom ICs, but I also get involved in microcontrollers, and CPLD/FPGA design when necessary, which is quite often. Some applications are often clearly digital or analog, but others are not so clear. Which approach you take is likely to depend on your skill-set. A digital engineer […]

Top analog IC stories of 2017
Here are the analog IC features that got the most interest from readers in 2017. The voltage follower or unity gain amplifier in a voltage divider Operational amplifiers have a very high input impedance, which means that they don’t suck in much current (ideally, none) at the inputs. Op amps also […]
