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 ...

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

Solar photovoltaic (PV) power generation demonstrated the largest absolute growth of all renewable technologies in 2022, surpassing wind for the first time in history, according to the International ...

The LP3946 is a stand-alone single cell Li-Ion charger with an integrated pass transistor and current sense resistor. In addition to its charging function, it can be used in low dropout (LDO) mode.

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 ...

The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...
