In designs using multiple LED strings such as brake lights, daytime running lights, rear lights and other automotive lighting applications, current-balancing circuits supply equal current to all LED ...

A technical paper titled “Tunnel Junction-Enabled Monolithically Integrated GaN Micro-Light Emitting Transistor” was published by researchers at the Ohio State University and Sandia National ...

[michimartini] over on Hackaday.io loves playing with multivibrator circuits, and has come across a simple example of a ring oscillator. This is a discrete transistor RC-delay design utilizing five ...

Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...

Schematic and operation of a capacitorless active-matrix micro-LED pixel, where a single memristor (1M) substitutes both the storage capacitor and the driving TFT. The compact 1M cell can be ...

The single cell led flashlight circuit is a self-oscillating boost converter. A typical white LED has its best power-efficiency combination at about 20mA, and needs about 3.3V. This makes for a power ...

A joint research team led by Professors Donghee Son and Jin-Hong Park at SKKU has developed a stretchable, self-healing, and reconfigurable electronic circuit platform that can autonomously recover ...

Transistors are the fundamental building blocks behind today's electronic revolution, powering everything from smartphones to powerful servers by controlling the flow of electrical currents. But ...
