Source-measure units (SMUs) are more than the next generation of power supplies. They are fast-response read-back voltage and current sources with high-accuracy measurement capabilities, all tightly ...

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 ...

“Spoiled for choice” is an understatement when it comes to DC power supplies and AC sources. There literally are hundreds of models and options to choose from. Output voltage and current generally top ...

Voltage and power integrity are becoming increasingly critical and challenging for chip designers and architects, regardless of which process technology they are using or which market they are ...

This design idea reprises another “1A, 20V, PWM controlled current source.” Like the earlier circuit, this design integrates an LM3x7 adjustable regulator with a PWM DAC to make a programmable 20 V, 1 ...
