This application note shows how to use linear voltage regulators to provide a constant current. Two circuits are presented, one for high-side and another for low-side current sources. The MAX1818 and ...
A cascode configuration reduces reference modulation error in a 4-20 mA current mirror, improving active impedance by orders of magnitude.
Download this article in PDF format. High-brightness visible-light LEDs (VLEDs) require a constant-current source. This simple, RFI-free circuit takes advantage of the normally-on properties of the ...
Linear Technology’s LT3092 is a 0.5- to 200-mA, twoterminal, low-temperature-coefficient, constant-current- source IC. Conceptually, it’s simple, but there has never been an IC like it. Linear ...
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 ...
