With two pre-amps you can make a stereo preamp or ‘hybrid’ power amplifier. It is important to note that tubes are high voltage low current and from a conventional/modern circuit design ...

While the RF designer uses an array of advanced analytical tools and techniques to design an RF matching circuit for a 2 GHz power amplifier, an oscillation at 60 MHz is passed off as a minor ...

Can you do the same thing with electronic circuits? The answer–perhaps not surprisingly–is yes. Consider this simple common emitter amplifier (I modeled it in PartSim, if you’d like to open ...

Our favorite integrated amplifiers in 2024 include models from Cambridge Audio, Naim, NAD, Unison Research and more.

Noise analysis is very important in many analog and RF receiver circuit design since the received signals are very weak. In case of differential amplifiers the noise appear as common mode signal and ...

Class A devices feature a design in which the output stage passes current ... Single supply devices can operate with only one power supply. Audio amplifier chips with an embedded control circuit shut ...

Peter Walker’s wonderful circuit innovation for the original 303 remains at the new amplifier’s heart. A breakthrough in transistor amp design required less negative feedback as well as ...

Therefore, TIA stability and self-oscillation become key design considerations ... The transimpedance-amplifier stage is the common key circuit element between all three applications considered.
