Liquid-based cooling of electronics is rarely the preferred solution to thermal management, but it may be the only one; improvements in the underlying components may make it a more-palatable option.
When Vendor Numbers Defy Ohm's Law

The basic component values associated with the low-voltage AC charging circuit for the Ring2 video doorbell have me wondering if I am missing some basic understanding.
What's the Impact of Medical-Design Mandates?
Analog Angle 10/24/2018 1 comment
Medical devices from wearable to big machines embody leading-edge technologies, but they also must meet an enormous menu of safety, power, and EMC standards that have major effects on design innovation, flexibility, and time to market.
My Personal STEM Experiment

It’s hard to find viable, simple, tangible demonstrations of STEM-related concepts, but an old-fashioned Received Signal-Strength Indictor (RSSI) and TV provided one.
Is Graphene the Next Silicon?

Simple things like proper labeling of cables and additional annotation is an easy way to make a big difference in debugging of prototypes and pilot units.
Gate Drivers Get Some Deserved Attention
Analog Angle 3/22/2018 Post a comment
Deciding which power-device driver to use may not seem like a big deal, but how well it matches the power device and design objectives is an important factor in overall performance and reliability.
More to Microphones than MEMS

MEMS-based microphones are way ahead of traditional electromechanical microphones in unit volume; the classic designs still have their unique roles—but for how long?
Go ASIC for Analog?

The self-healing circuitry of science fiction isn't here yet, but there's significant research underway at NASA and universities to make it into a reality
I checked another item off my ‘Bucket list’ last week. NASA enabled me up to ‘fly’ the Mars Orion simulator!
A transimpedance amplifier (TIA), which takes the current from a photodiode and converts it into a usable voltage with low output impedance, can provide effective gain for a photodiode signal.
The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally given the name: "Current Drive" circuit, so we'll call it that for now.
EnOcean has enabled millions of wireless light switches that do not contain batteries and has now introduced the “Battery-free by EnOcean” seal to highlight the self-powered switches’ benefits at a glance.
In October, a New York City Police Department officer on Staten Island wore a body camera that unexpectedly began smoking and caught on fire.
