High efficiency white LEDs have advanced to the point where they can replace glow bulbs and other light sources not only as indicators, but also for illumination. While many of the claims made about ...

APDs (avalanche photodiodes) or APDs, are common components in laser-based fiber-optic systems for converting optical data into electrical form. The bias voltage and current measurement requirements ...

Designed to illuminate the work area when tracing ac circuits in dark areas or behind equipment, the SenseLite is a battery-powered flashlight with a noncontact ac voltage detection circuit and a red ...

CMOS current mirrors are pivotal in modern electronic circuitry, providing accurate current replication that is essential for biasing, amplification and active loading in a myriad of integrated ...

If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is ...

Transmitting information using light is more energy efficient than using electrical signals. Unfortunately, for small-scale applications, light-based encoding through electro-optic modulators (EOMs) ...
