Here is the simple diode circuit and the I-V characteristic curve of a diode. The circuit shows a diode connected in series with a resistor and a DC voltage source. The I-V characteristic curve ...

There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...

Abstract: We propose a low-temperature polycrystalline silicon thin-film transistor (TFT)-based micro light-emitting diode (μLED) pixel circuit using quaternary digital pulse width modulation (PWM).

A Planet Analog article, “2N3904: Why use a 60-year-old transistor?” by Bill Schweber, inspired some interest in this old transistor and how it’s commonly used, and if any uncommon uses might exist.

A transistor tester can be a handy addition to your electronics workbench. This versatile transistor tester design, first presented a decade ago, enables you to quickly assess the functionality of NPN ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

The circuit may be powered with a DC-Adapter $12VDC$ or $24VDC$, obviously the maximum measurable zener voltage depends on the supply voltage. The circuit allows you to test different types of diodes, ...

Here is a simple circuit of TV to FM converter. With this simple one-transistor BF494 circuit. you will be able to receive FM and VHF stations on your old Black And White TV sets. The circuit uses ...

Abstract: ESD is a well-known reliability aspect in Si technologies, but GaAs devices are more susceptible to ESD damage than the silicon devices. In this study, the ESD survivability of the InGaP HBT ...
