PWM is a simple, cool, cheap, cheerful, and (therefore) popular DAC technology. Excellent differential nonlinearity (DNL) and monotonicity are virtually guaranteed by PWM...

A project in the UK and the Netherlands is using Large Language Models (LLMs) to create hardware designs with a technique it calls...

The circuit below will trickle charge a four cell pack of AA or AAA NiMH batteries...

Some industrial applications require you to feed a low-power dc/dc converter from a three-phase source and possibly to deal with line-to-line voltages of 200 or 400 V rms. Further, the neutral terminal of the ac source may be unavailable for connection...

High speed analog-to-digital converters are by definition devices that sample an analog signal and, as such, must have sample clock inputs. Some system designers that utilize ADCs have observed a slower than expected startup from the time the sample clock is initially applied...

An inverter provides power backup for mains-based appliances in the event of a power failure...

Renesas Electronics Corporation introduced the RA2L2 microcontroller group with ultra-low power consumption and the industry’s first support for the new UCB-C Revision 2.4 standard...

The electronic circuit injects a precise 1 Amp of current into any unknown resistor, up to about two ohms. Two alkaline C cells power the complete circuit...

This article discusses the applications of an operational amplifier for electrochemical gas sensors such as ethanol and carbon monoxide...

Recently, I published a Design Idea describing a bidirectional current mirror using just two transistors and a diode. That circuit works well in some applications, like the one shown in the DI itself, but it nevertheless has limitations due to various error-introducing effects...
