Characterizing solarcells, power-management devices, high-brightness LEDs, and RF power transistorsoften requires tens of amperes, but power MOSFETs and IGBTs (insulated gatebipolar transistors), can ...

Many process-control sensors, such as thermistors and strain-gauge bridges, require accurate bias currents. By adding a single current-setting resistor, R 1, you can configure voltage-reference ...

Over on his YouTube channel [Aaron Danner] explains biasing transistors with current sources in the 29th video of his Transistors Series. In this video, he shows how to replace a bias resistor (and ...

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 ...

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 ...

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 ...
