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 ...

IC 1 ’s output drives an enhancement-mode N-channel power-MOSFET, Q 1, an STMicroelectronics IRF530, such that the voltage across the sense resistor equals the positive-input voltage. The voltage ...

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 post answers the question “What are different types of controlled sources?”. Controlled sources are sources, that are dependent on some parameters of the system. There is four types of controlled ...

Abstract: With the development of laser-based sensing and communication technology, the application of semiconductor lasers in industrial production and scientific and technological research 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 ...
