For applications that require or desire a computer controlled variable current, the use of a digitally controlled potentiometer and a current mirror with degeneration provides a low cost solution. One ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

1. Bob Pease used an LM334 current source to servo the current from a PNP transistor through an LED diode. The LM334 will draw current into its V+ pin until the voltage on the R pin reaches 0.068 V.

Many of the technologies we rely on, from smartphones to wearable devices and more, utilize fast wireless communications. What might we accomplish if those devices transmitted information even faster?

Sometimes we need a transistor with a different characteristic than the normal one for max voltage and current of the collector, maximum power dissipation and amplification. This can be done by using ...

In analog layout design, precise layout matching techniques are crucial to ensure the accuracy and performance of the circuit so that transistors exhibit similar electrical properties (i.e.
