An SCR topology transmogrifies into BJT two-wire precision current source with a self-resetting fault-current limiter.

As power electronics switching techniques advance, there is an increased need to accurately measure current for feedback control and system monitoring. There are several methods to achieve this, and ...

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 ...

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 ...

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 JEDEC 35 Standard (EIA/JESD35, Procedure for Wafer-Level Testing of Thin Dielectrics) describes voltage ramp (V-ramp) and current ramp (J-ramp) tests to monitor oxide integrity. These tests are ...
