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 ...

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 ...

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 ...

Author’s note: This article shows how to derive circuit gain equations via a signal flow graph. With practice you may be able to write a gain equation by locating signal paths and loops in the ...

Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...
