by Matthew Ballance, Mentor, a Siemens Business Register tests are a very useful smoke test at all design levels — from IP to subsystem to SoC. While the built-in register-test sequences in the UVM library are useful at the IP level, capturing register-test intent in a PSS model makes register-test functionality portable from the IP […]
Considerations for improving 3D NAND performance, reliability, and yield
by Mark Puttock, Director Advanced Deposition and Plating, office of CTO, Entegris Even as 3D NAND races toward maturity and becomes a mainstream technology, chipmakers know there is still more to achieve to meet worldwide consumer and business data demands at lower costs, given the extreme complexities involved. As with previous technologies, focusing on process […]
How to create energy-efficient IIoT sensor nodes
by Noel O’Riordan and Tommy Mullane, S3 Semiconductors When you’re designing sensor node devices destined for the industrial internet of things (IIoT), chances are they need to be battery-powered. And given the number of these expected to be deployed, and their often-remote locations, changing or charging a battery frequently isn’t an option. Your device, therefore, needs […]
Smartphone biosensor tracks heart rate, blood pressure, oxygen sat, and more
MediaTek Inc. today unveiled MediaTek Sensio, the first 6-in-1 smartphone biosensor module. MediaTek Sensio is a powerful advanced health monitoring solution which makes it easy to track heart rate information, blood pressure trends, peripheral oxygen saturation levels and more. Available as an embedded module in smartphones, MediaTek Sensio makes it possible for consumers to quickly check and […]

Fixed point vs Floating point
Various types of processors (DSPs, MCUs, etc.) have the ability to do math using floating point numbers, but what exactly does this mean? In general, floating point math offers a wider range of numbers and more precision than fixed point math. Knowing the difference, and when to use which type of math can make a […]
DEMUX, MUX, and Decoders: How To Expand I/O
The relentless march of technological progress has given engineers increasingly smaller and more energy efficient microcontrollers to use in their designs. These benefits do come with a cost, however. Physically smaller packages have less room for I/O pins meaning fewer peripheral components can interface with the microcontroller itself. Fewer peripherals means less functionality which tends […]

PWM using Controller – I working on one project which requires the following condition: Analog voltage and PWM […]
Memory technology from Floating Gates to FRAM
There are two basic types of memory: volatile and non-volatile. Volatile memory loses its content and becomes a blank slate whenever power is completely removed. However, volatile memory doesn’t need much power and can maintain its contents with a small battery. Non-volatile memory retains its contents even if power is completely removed. SRAM and DRAM […]
What is an open drain on a FET device and how is it used?
If you are working with an integrated circuit (IC) and the datasheet mentions an open drain or open collector, that’s engineering speak for a current sink on an output pin. For those unfamiliar with the terminology, a “current sink” means that the current is flowing into the pin (or node, etc.), not out of the […]
