Bjt Definition and 210 Threads

i want to know why at some point the low output voltage for a bjt biased between 0 and 5 on the base and voltage 5 at the drain ranges between 0.225v and 75mv so which of them is the low voltage pz answer me now i have a project to deliver

I was researching a bit about the common-base configuration of a BJT transistor on wikipedia, and I found this quote: "This arrangement is not used as much as other configurations in low frequency circuits but is often employed for amplifiers that require an unusually low input impedance, for...

How does a small change in base current result in a large change in collector current in a BJT? Please explain in terms of movement of electrons (in NPN). Most textbooks I have referred say that the reason is low resistance of emitter-base and high resistance of collecter-base. However i cannot...

We've base biased circuit, voltage divider, emitter bias, and collector feed back bias...I'm looking for resources, to compare those 4 types, what are the advantages of each type, why is it used, and where... I know BJT's work in amplifiers, but i need more detail concerning those different...

Hi, I'm new here. can somebody put here an a schematic of Class AB, D,G or T. I need an audio amplifier that work with bjt and mosfet simultaneously, i think that kind of amplifier is class g, but I'm not sure,for example i saw an 5000w amplifier with 2sc5200 and his pnp pair working with...

I thought that the base recombination current (say in a pnp bjt) was the current caused by the electrons that come up the base wire to compensate the loss of free electrons from the recombination process in the base. But recently I read that this are actually two different currents that sum up...

I'm really confused between saturation and amplifier. When will the transistor work in saturation mode and in amplifying mode? Resistors are the matters. We chose the resistors so that the transistor will work in saturation or amplifying. How can we chose?

In order to use BJT as a switch, it's very popular to do as the picture. In the picture, V_B > V_E, so there's a current flow I_BE control the I_CE. In the other way, V_B > V_E generates the current I_CE, and the lamp will light on. But, I change the connection a little: I'll let the V_B...

Can anybody explain to me what and how a phase shifter can be implemented using BJT.or give me the site which can get more details about this.

Hi, I know how to drive a transistor as a switch, but I am not very sure how to perform voltage and current calculation and analysis at the collector to emitter side. Basically what I know is that if the base is biased at 0.7 V, the transistor will be switched ON and current will flow...
