FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...

This isolated current regulator produces currents up to ±10 A, depending on load configuration, with current determined by the tap chosen and a 0- to 1-V control voltage V ISET. When measuring the ...

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 ...

In electronics, a Norton amplifier—also known as a current differencing amplifier (CDA)—is a specialized analog circuit that ...

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 ...

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 ...

It’s often necessary to connect point-of- load (POL) dc/dc power supply modules in parallel to get a sufficiently high-current output for applications such as test instruments, blade servers, and so ...

ABB has released the Switching Control Sentinel (SCS) device designed for high-voltage circuit breakers. Voltage and current transients generated during switching of high-voltage circuit breakers are ...
