transistors - Difference vcc and vc, vbb and vb, vee and ve ...
Apr 13, 2022 · As far as I know, potential difference (voltage), that's mean it needs two point to measure it. Then what does vc or ve only or vb only? If vce means potential between vc and ve? And what …
Why should Vbb not exceed the barrier potential values?
Think what would happen if we didn't follow the advice and applied 1 V across base and emitter. Realize that the Base-Emitter junction behaves very similar to a diode. What does the Voltage-current …
How can I calculate a transistor's IB, VBB and VEE from the given ...

What is the value of Vbb in the circuit given below?
Jan 18, 2017 · An NPN transistor is shown the figure. Here we can see that only Vcc is given. I am wondering what the value of Vbb is, as I want to calculate the base current.
Why is a DC base voltage needed to attain faithful amplification?
Nov 4, 2014 · The bias voltage generally needs to be somewhere between the positive and negative rails of VCC. It doesn't have to come from a separate supply, however. It may be (and often is) …
amplifier - How do I choose a transistor for a VBE multiplier ...
Jan 3, 2024 · I am currently designing a 150 W audio power amplifier for 12 ohms, so 60 V peak to peak and 5 A. I'm using a C5198/A1941 pair for AB amplification with D669/B649 in a Darlington …
NPN Transistor Base Current Calculation from Beta, Vth, and Rth
Nov 28, 2023 · I mean if the collector current is approx the emiter current (B+1)=B, the collector is Beta times Ib where Ib is given as (Vbb-Vbe)/Rb Why is Beta inteh denometer instead of the numerator …
terminology - The various terms for voltage - Electrical Engineering ...
Most of that notation is going to be arbitrary. However, Vdd and Vcc are commonly references to your negative supply and positive supply, respectively (some devices require such configuration, like an …
Why is the collector voltage must be bigger than the base voltage to ...
Here I don't get why VC > VB is necessary Actually, it is not : If the transistor is saturated, you can have (for example) Vbe=0.6V and Vce =0.3V. When NOT saturated, you will have Vc>Vb. It looks to be if …
Vb and Vbe of a transitor - Electrical Engineering Stack Exchange
Sep 23, 2023 · Is VB and VBE, of a transistor the same? If not, how is Vbe generated? ....and must the base voltage of a transistor be equal to 0.7 or can it exceed this value.
