What are the applications and measurements of S-parameters? (Part 2)
Part 1 of this FAQ was a basic introduction to the context and concept of s-parameters. Part 2 looks at their measurement and application and relationship to the time domain. Q: How do you actually measure s-parameters? A: In general, except for approximate measurements, you cannot use a spectrum analyzer alone for this frequency-domain test. […]
MEMS-based absolute pressure sensors target altimeter apps
Würth Elektronik presents a very compact MEMS-based (Micro-Electro-Mechanical Systems) absolute pressure sensor: The 2.0 x 2.0 x 0.8 mm sized WSEN-PADS measures pressure in the range between 26 and 126 kPa. Its output data rate can be selected between 1 and 200 Hz. The sensor contains an ASIC (application-specific integrated circuit) and a temperature sensor. […]
Ultra-thin piezo speakers handle high SPL, large frequency range
TDK has expanded its lineup of ultra-thin PiezoListen speakers with new types featuring a wider dynamic range and higher sound pressure level (SPL) in the low-frequency range, even at voltages up to 24 VP-P. The PiezoListen series of piezo speakers now includes the PHUA6630 wide dynamic range speaker with an operating frequency range of 400 […]
Fluxgate compasses, Part 2 – Issues and enhancements
Part 1 of this FAQ examined the underlying context of fluxgate compasses and navigation, as well as the basic principles of the fluxgate design. This part looks at additional fluxgate-compass issues and advances in their implementation. The fluxgate compass is fairly simple in principle. However, as with all things related to magnetism in general and […]
Fluxgate Compasses, Part 1 – Context and principles
Despite the availability of GPS and inertial measurement units, the compass in an electronic fluxgate implementation is still a viable and needed navigational tool. The classic magnetic-needle compass is not getting much respect or attention these days. Between the Global Positioning System (GPS) and the Inertial Measurement Unit (IMU) system, the compass – whether it […]

Trans-impedance amp handles 64 Gbaud-based 400G coherent apps
Integrated Device Technology, Inc. (IDT), a wholly-owned subsidiary of Renesas Electronics Corporation,introduced its new GX36x20 64Gbaud linear Trans-Impedance Amplifier (TIA) series, in die form. The GX36x20, along with the Renesas NR5195 photodetector diode, offers a very efficient and high-performance receiver solution for 64 Gbaud-based 400G coherent applications. Attendees at ECOC 2019 can see samples of […]
Printed Circuit Boards, Part 3: Vias and multilayer boards
Part 1 of this FAQ series looked at the ubiquitous FR-4 PC board as well as other PC board issues, and Part 2 reviewed highlighted some of the board issues and the widely used FR-4 PC board substrate. This third part looks at advanced PB board issues such as vias and multilayer boards. Q: How […]
Solving the end-of-life headache
by Edel Griffith, Adesto Technologies The technology business rarely stays still as new technologies emerge, and newer versions supersede older products. Semiconductor devices have been around for over half-a-century now, and the pace of technological change is, if anything, increasing. While this pace of innovation brings many benefits in terms of enhanced functionality and increased […]
