When it comes to getting signals from an analog world into our computers, most of us don’t give much thought to how the hardware that does the job works. But as it turns out, there are a number of ...

However, if the successive-approximation circuit needs to operate at a relatively high clock rate to deliver samples quickly enough, the higher threshold voltage needed will increase the energy needed ...

Energy-efficient successive approximation register (SAR) analog-to-digital converters (ADCs) represent a rapidly evolving field in microelectronics, where substantial progress has been made in ...

[Igor] made a VU meter with LEDs using 8 LEDs and 8 comparators. This is a fast way to get one of 8 bits to indicate an input voltage, but that’s only the equivalent of a 3-bit analog to digital ...

Low-power successive approximation register (SAR) analog-to-digital converters (ADCs) represent a critical technology in modern electronic systems, seamlessly bridging the analogue and digital realms ...

Editor's note: We will publish this article in four sequential parts leading up to our “Ask the experts” session on Precision Voltage References on May 21. Alan Walsh will be one of our experts. The ...

A poorly designed reference circuit can cause serious conversion errors. The most common manifestation of a reference issue is repeated or “stuck” codes from the ADC. This happens when noise on the ...
