Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

The circuit of Figure 1 provides a "diode-OR" function for applications that must switch automatically between the main and backup supply voltages. Such applications include battery-backed memory ...

If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs, switch a ...

The transistor has been around since the nineteen forties. In fact, the FET (Field Effect Transistor) was actually developed before the more common bipolar type. Bipolar transistors use semiconductor ...

This FET audio mixer is an example of FET’s versatility. FETs are originally designed for high frequency applications but they can be used for audio frequencies and in fact they perform excellently in ...

In a typical automotive video application, the video digital-to-analog converter (DAC)—from a rear camera or DVD player, for example—is followed by a low-pass reconstruction filter and an amplifier ...
