Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are going to ...

We’ve previously remarked upon a generation lucky enough to be well-versed in microcontrollers and computersised electronics through being brought up on the Arduino or the Raspberry Pi but unlucky ...

In this letter, we first introduce the two amplification circuits with discussions of gain, sensitivity, bias behavior, and noise. We compare the basic performance and operation of the two amplifiers ...

In this paper, a band-stop filter (BSF) is employed to suppress all signals between the two operating bands with a high level of attenuation. The proposed BSF structure comprises spiral lines and ...

It may not be to everyone's taste, but this brand new monobloc amplifier from McIntosh cleverly blends both vacuum tube and solid-state technology in one chassis. If you’re not a serious audiophile ...

The 2N2222 and BC549 transistors are two old components that are still universally used in the vast majority of electrical circuits today. Their applications include amplifiers, filters, impedance ...
