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 ...

Reading an article about the first transistorized Hi-Fi amplifier, [Netzener] got the itch to make one. But what to use for the starting point? Enter an old Radio Shack P-Box stereo amplifier kit.

Amplification is a process of increasing the signal strength by increasing the amplitude of a given signal with out changing its characteristics. Here we will concentrate how transistor is used as ...

Despite recent improvements in the performance of RF LDMOS field-effect transistors (FETs), temperature drift and aging continue to affect the efficiency and linearization of power amplifiers using ...

Researchers from the University of California – Riverside and Rice University have made the first single-transistor amplifier from graphene. The device is better than conventional amplifiers thanks to ...

Abstract: Depletion mode transistors, such as GaN HEMTs, are widely used in high-power RF applications. High-power RF amplifiers using GaN HEMTs are biased with large drain-source voltage, and a high ...

While this op amp may actually have some utility, it is intended mainly as an educational exercise. I guarantee that if you build and experiment with this circuit, you will learn and appreciate what ...

Usually targeted at audio applications, these circuit blocks find homes in all types of designs. Here’s a quick study of their operation and properties. Two of the most often used amplifier building ...

Abstract: The relationship between Fe concentration in the buffer layer and breakdown voltage of an AlGaN/GaN on SiC HEMT transistor has been investigated to achieve operation of the device in a UHF ...
