Hi, so I built a similar circuit on a breadboard. Carefully measured all voltages, resistances and currents. Base current measured was 12uA. Applied all measurements to the formula. Resulting calculated base current is 12.1uA. Have to love it when the math lines up with the real world!

This is a great piece showing Thevenin's equivalent and the biasing of a transistor. I am taking Cleveland Institute of Electronics Advanced Engineering Course and will add this to the transistor books. I will teach this is Asia. I was a staff engineer/scientist at IBM with patents and recognize the great work that you have shown here. Great job.

I'm not sure that the Base Voltage of 3.7 V is correct here, because it lacks the voltage input from the V-source/voltage divider. It seems that the BASE VOLTAGE is the Thevenin Equivalent voltage of 4.9V. It can't be both, and 4.9V satisfies the KVL loop for the Base-Emitter loop and represents the first entry into the big equation for Base current. The Thevenin equivalent voltage is the voltage produced by the source voltage and the voltage divider. The 3.7V value did not affect the other calculations, so I think this is a minor error. Any other input on this welcome.

I've been trying to solve this without find the Thevenin equivalent as was done in the video. Using KVL in the "finding the I_B" stage, I initially used: V_CC = I_1R_1 + V_BE + I_ER_E and from that have gotten as far as: I_B = (V_CC(R_2/(R_1 + R_2)) - V_BE) / ((β + 1) R_E) It's basically the same as the one that was used in the video, however I am missing a term in the denominator which is the equivalent parallel resistance between R_1 and R_2. Can someone try to point out how I could fit that in this equation? I feel like I should have included it in the initial KVL equation I used, but I don't know where (and how) it should go. EDIT: After searching a bit, I realize that the equation should've been: V_CC = I_1R_1 + I_BR_B + V_BE + I_ER_E R_B is the parallel resistance I'm missing. However, I'm still struggling to intuitively think of the *existence* of R_B along that path.
@abdoelkady99743 жыл бұрын
Firstly thank you for the great tutorial secondly if we calculated the half of Ic saturation it won't equal Ic of this circuit so does that mean it ain't a midpoint biased circuit or is it that my calculations are wrong or is there some other thing i don't know ?
@scottbender73543 жыл бұрын
Going the route of solving for VB with thevenin, then solving for VE using difference between base and emitter voltage, then using the drop over the emitter resistor to solve for emitter current, then finally solving for IB and IC using beta relations will get you a vastly different answer. Why is that?
@scottbender73543 жыл бұрын
I believe transistors are actually non-linear devices, so thevenin's theorem would not be applicable here.

Think about what happens at the nodes where two transistors are in parallel. How are the currents and voltages related? Try to use Ohm's law and Kirchhoff's current law to find the total current across both resistors, and then the equivalent resistance would be R_equivalent = V/I_total.
