Andreessen Horowitz leads a Series A investment in Diode Computers, which translates printed circuit board layouts into code.

By combining 49 of them he’s put together a soda bicarb diode steering circuit for a 7-segment display capable of showing the digits 0 to 9.

Laser diodes are widely used in optical engineering applications, such as fiber optics, laser scanning, and optical communication. However, designing a laser diode driver circuit can be ...

The circuit is simple enough: it uses a capacitor, a resistor, and a pair of diodes (one of them a zener diode). He uses this basic circuit to drive simple regulators with input and output filter ...

Figure 4 shows an assembled zener-diode-tester circuit. The zener diode under test is On Semiconductor‘s BZX55C15RL, which has a working voltage of 13.8 to 15.6V. The voltage in Figure 4was measured ...

Summary <p>When the signal applied to such electronic devices as diodes and transistors is large in comparison with the bias level, they show ON&#x2010;OFF behavior, functioning like a switch. The ...

Expensive semiconductor laser diodes have no tolerance for fast voltage or current transients. To minimize the risk of damage, a standard JFET-clamp circuit shorts the laser when there is no supply ...

The value of R1 is determined by the maximum laser current required (in this case, 250 mA), adjusted by the laser diode's typical forward voltage of 2.0 V as given on the datasheet. Solving for R1 ...
