This circuit was designed to meet a medical application’s requirement to drive a laser diode with reasonable precision and a minimum of components and footprint (the device is now in clinical trials).

As a response to a need for a simpler SMD package and higher current ratings, Semitec have now introduced the new S-series CRD range. The new SOT23 package offers constant current values from 0.1ma ...

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 ...

Download this article in PDF format. When you connect the gate to the source of a JFET (junction field-effect transistor), it becomes a two-terminal current source. The current that will flow is ...

This lab seeks to illustrate the fundamental operation of uncontrolled rectifier circuits. The waveforms associated with these circuits are visualized using simulation and experimentation. The circuit ...

The LM334 is not only an adjustable current source, but it is also a rectifier. Right on the front page of the TI data sheet are the words: “Reverse applied voltages of up to 20V will draw only a few ...
