If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is ...

In order to test and characterize optical front end circuits, a controllable, high bandwidth, microamp-level current source is needed. However, most optocouplers on the market have large CTR variation ...

Demand for voltage-controlled current sources (VCCSs) and multipliers in a wide spectrum of electronics and communication devices always seems to exist. The multipliers employed in circuits like the ...

Power grids (PGs) have consumed an increasingly larger percentage of routing resources in recent process node generations, due to lower maximum current limits imposed by the foundry. It is not ...

Download this article in PDF format. When you connect the gate to the source of a JFET (junction field-effect transistor), it becomes a two-terminal current source. The current that will flow is ...

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 ...

The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...
