Linearly variable two-wire loop current generator
Circuits such as the design described here implement useful tools for a diversity of calibration and testing applications.
A two-wire loop current generator is a useful tool for the testing, calibration and commissioning of current-to-pressure…

The ASIC design remake in the AI era
The traditional ASIC design model—focusing on relatively stable standards and well-defined functions—is now under pressure. That’s partly because AI workloads are highly diverse, compute-intensive, and tightly coupled to software behavior…
How to implement OTA firmware update on MCUs
Here is how design engineers can implement over-the-air (OTA) firmware updates for a microcontroller using the “staging + copy” method. The microcontroller—NXP’s RW612 in this design case study—relies on external serial flash. The…
BJT is accurate sensor for absolute temperature in Kelvin and Rankine
Simple math implemented in a (very) simple circuit. What’s not to like?
A very cool (also warm!) property of the base-emitter junction of (most) small signal BJTs is the ΔVbe temperature-sensing effect. ΔVbe temperature measurement is…

What’s the impact of AI on analog design
It seems any expert who can spell “AI” has an opinion on its potential impact. There are countless predictions out there, many made with precision and confidence, and they are often contradictory.
Depending on who you listen to, AI will…
Simple circuit interfaces differential capacitance sensor
This design based on an SR latch and two RC networks is, unlike many alternative solutions, neither complex nor expensive.
Single and differential capacitance sensors are widely used to measure linear and angle displacement, pressure, proximity,…
Electronic biosensing: A quick take on ketone detection
Ketone detection may sound like the domain of biochemistry, but at its core, it’s also an electronics challenge: how do we translate a chemical presence into a measurable electrical signal?
The key lies in the ability of circuits to convert…
TP-Link’s Tapo H100: Smart sensing unencumbered
Three smart home hubs, from two different companies. All supporting both 2.4 GHz Wi-Fi and proprietary 900 MHz wireless links. How do they differ, and are similar? Let’s find out.
Last month, I told you about TP-Link’s Tapo Hubs and their…
Teradyne snaps up TestInsight to boost ATE for semiconductors
Automated test equipment (ATE) supplier Teradyne is bolstering its test solutions for semiconductor design by acquiring TestInsight, a provider of test program creation, pattern conversion, and pre-silicon validation tools used across ATE platforms…
Aliasing, the bane of sampled data systems
Aliasing is thankfully becoming a less frequent problem due to improved instrument designs. Users should still be aware of it to prevent time- and money-costly errors.
Aliasing is an ever-present potential problem in sampled data acquisition…
