Does the collector voltage have to be greater than the emitter voltage by few tenths of a volt for an NPN transitor
For an NPN transistor, does the collector voltage have to be greater than the emitter voltage by few tenths of a volt for it to be in active state? If yes what is the reason?
Also it says greater by a ...

MOSFET common source amplifier output impedance calculation
What I've read in microelectronic texts like Prof's Razavi's Fundamentals of Microelectronics is that for calculating output impedance, one has to make all independent sources 0, i.e., short all ...

Confusion regarding this Op-Amp circuit
So I have started learning about Operational Amplifiers. In case of idea Op-Amps,
Vd=0 as amplification is very large and Vo is limited by Vcc(the supply voltage).
Here in this inverting Op-Amp ...

How exactly does a transistor amplify the input current in CE configuration
I have gone through tons of forum discussions and videos and books but they all explain in terms of mathematical equations that factor the input by a 'larger than 1' number. What happens physically ...

is any other technology than semiconductor transistors or vacuum tubes that can be used as active devices?
I am curious to know if one can amplify a signal or make nonlinear active distortion to an electric signal without semiconductor transistor or vacuum tube technologies?
