In April 2012, EDN published a circuit by John Fattaruso that lets you quickly measure the drain-source saturation current and the pinch-off voltage of both an N-JFET and a P-JFET...

Quantum computers are among today’s most exciting emerging technologies, but their design, testing, and manufacturing require unparalleled care to avoid damaging their components...

Many different switching regulator topologies exist. Some, such as the classic stepdown converter, also known as a buck converter, are very widespread...

Generating analog sawtooth waveforms (linear ramp followed by a quick reset to zero) from digital timing signals is a common function. It usually requires a negative supply...

Fully integrated & protected GaN ICs with bi-directional loss-less current sensing delivers 4% higher efficiency, 15% lower system cost & 40% smaller footprint...

If you have a load with a variable or poorly specified resistance and want to regulate the power applied to it (a heater for example), merely controlling the voltage or current will not work, as in both cases the power P = I2R = V2/R depends on R...

Vishay Intertechnology introduced the industry’s first AEC-Q100 qualified rectangular ambient light sensor....

The LM4041 has been around for over 20 years. During those decades, while primarily marketed as a precision adjustable shunt regulator, this classic device also found its way into alternative applications...

The ever innovative and prolific Mr. Woodward has offered “PWM-programmed LM317 constant current source”, an intriguing programmable constant current source which elicited a lively conversation in its comments section...

Almost every wall power supply has no indicator showing whether current is consumed by the load or not. It seems that this was a shortcoming that was not only noticed by me...
