Recently, frequent Design Idea (DI) author Christopher Paul showcased an innovative and high performance true-two-wire current source using a depletion mode MOSFET as the pass device in “A precision, ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

At first glance, [RobBest]’s constant current source looks old school. The box is somewhat old-fashioned, featuring switches and binding posts. Most importantly, there’s a large analog meter ...

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 ...

Voltage and lesser-known current sources provide important IC, circuit, and system functions. This section continues the discussion of current sources and related topics. Figure 1. Circuits similar to ...

SSCBs based on WBG devices such as SiC or GaN can expand their competitive advantage in many applications. Traditional electromechanical breakers rely on electromagnetic action for short-circuit ...

Abstract: Constant current source that converted from voltage source has worse temperature characteristics, as typical BCD process does not support high precision and low temperature coefficient ...
