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 ...

It has long been known that the simple combination of a depletion-mode MOSFET (and before these were available, a JFET) and a resistor made a simple, serviceable current source such as that seen on ...

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 ...

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 ...
