Hi there! I'm having trouble understanding the transistor circuit analysis. Hope you could help me :) First I need to find the active region of the transistor. What I saw in the solutions was an assumption that the transistor is in saturation region and then: VBB=IbRb+Vbe+IeRe Vcc=IcRc+Vce+IeRe Why did the solver assume the transistor is in saturation mode, when he is supposed to find the active region? Next, I have to calculate the minimal RE needed for the transistor to be active. This time, they did refer to it as in active region. But, the equations remained the same. I thought that in Active region, it is supposed to reverse: VBB=IbRb+Vbe+IeRe Vce-IcRc-Vcc=IeRe Why isn't there any change in the equations ? the BC diode is supposed to be in reverse mode, isn't it ? Thank you!
