In a negative-feedback loop, IC1 adjusts the gate of Q1 so that current flows through R1, Q1, and the laser diode. When the current through R1 drops the feedback voltage to +3.5 V, the circuit is ...

Diodes are critical components for a broad array of applications, from power conversion equipment, to radios, logic gates, photodetectors and light-emitting devices.

Most modern electronic devices consist of several key components: transistors, capacitors, resistors, inductors and diodes. Often, they are supplemented by additional components like crystals and ...
