Short-circuit protection is an obvious requirement for a power supply, especially when its load connects to a cable that's subject to damage...

Whether its buck, boost, or buck/boost, internal or external switch, milliamps or tens of amps, a literal cornucopia of programmable output switching regulator/converter chips are commercially available...

Figure shows how to position a mechanical device into four discrete positions but with only two free outputs and one free input from the control system...

High precision op amps enable system designers to create circuits that condition signals (amplify, filter, and buffer) while maintaining the precision of the original signal. When information is contained in very small variations of the signal, it is critical that op amps in the signal path perform their operation while contributing very little dc and ac error...

For the heating and cooling elements common in industrial systems, resistance is not a fixed quantity. These elements include such devices as positive-temperature-coefficient heaters and thermoelectric coolers...

A free energy collector circuit helps to convert surrounding radio frequency waves to electric power and can provide 40 watts to 10 watts indefinitely...

Instead of the conventional approach of backing up a DAC with an amplifier to boost output, this design idea charts a less traveled by path to power...

Using the MAX4373 high-side current-sense amplifier, a circuit can be designed with a voltage range to 28 V...

Figure is a cheap and cheerful voltage inverter I offered awhile back in “A simple, accurate, and efficient charge pump voltage inverter for $1”...

ADC circuits that resolve signal into 20 or more bits need a low-noise signal source for measuring parameters such as harmonic distortion or effective number of bits...
