Just as the common emitter amplifier and common base amplifier each tied those respective transistor terminals to a fixed potential and used the other two terminals as amplifier input and output ...

Both input and output impedance are quantities that you can often look up in the datasheets of a single component, figure out yourself for a transistor amplifier circuit, or even measure yourself.

To obtain reliable input resistance data, I had to reduce the source resistance to 0.1Ω and connect via a Kelvin connection. Input resistance is surprisingly easy to determine experimentally by simply ...

There appears to be 16 large transisitors which were mounted to the heatsink of this amplifier. It is a Planet Audio 4 channel car audio amp. From some quick Google searching, it looks like I ...

This hf circuit theory can be used to identify spurious resonances or oscillations in feedback amplifier and discrete transistor circuits, such as photodiode-input trans-resistance op-amps or emitter ...

Single transistor holds the potential to power a high-performance amplifier with the right components and setup. By following precise techniques, this transformation enhances audio output ...

Back in the '60s, there was an intriguing circuit article titled "Starved-Circuit Amplifier" published in Popular Electronics magazine. It used a sharp cut-off pentode with a ...

Why you should ditch your Bluetooth speaker for the smooth, sweet and surprisingly affordable sound of a vacuum-tube amplifier.
