Current Sources
https://www.electronics-lab.com/article/current-sources/
Introduction In the continuity of the Voltage Sources tutorial, we present in this article the Current Sources, which are the second type of electric sources we will look at. Similarly to what has been done for the voltage sources, we will first introduce the concept of ideal current sources where their particularities and characteristics are […]
Thevenin’s Theorem
https://www.electronics-lab.com/article/thevenins-theorem/
Introduction In this tutorial, we present a powerful method that can simplify through some transformation steps, complex circuits into elementary circuits and this method is commonly known as Thevenin’s theorem. Originally, it was the German physicist Hermann von Helmholtz who first demonstrated the theorem in 1853, but history kept the name of the French engineer […]
Ultra-Low Dropout Linear LED Driver from Diodes Incorporated Extends Lighting Strips
https://www.electronics-lab.com/ultra-low-dropout-linear-led-driver-diodes-incorporated-extends-lighting-strips/
Diodes Incorporated today announced the BCR430UW6 linear LED driver with ultra-low dropout voltage and constant current regulation between 5mA and 100mA. This combination allows more LEDs to be driven from a low supply voltage, making the BCR430UW6 suitable for applications that require multiple LEDs to operate together, such as signage illumination and architectural lighting for […]
Adjustable constant current source
https://www.electronics-lab.com/adjustable-constant-current-source/
Dilshan Jayakody has published a new build: The current source introduced in this article is capable to handle current up to 6A with maximum input voltage of 50V. This is an operational amplifier based adjustable current source and it uses LM358 in a general voltage follower configuration. To handle large currents we use four 0.1Ω […]

Precision programmable current source uses two ICs
https://www.electronics-lab.com/precision-programmable-current-source-uses-two-ics/
by Stefano Salvatori & Pietro Oliva @ edn.com: This Design Idea mates a precision current source IC with precision difference amp chips to create a programmable current source or sink. The resistor-programmable current source/sink in Figure 1 illustrates the basic topology, taking advantage of tightly matched on-chip resistor ratios instead of relying on absolute tolerances. Precision programmable […]
