However, looking at the circuit more intuitively, the Vcb voltage is simply the difference in potential at the collector of the transistor relative to our base, while the Vbe the potential difference between the base and the emitter The base region is between the collector and emitter regions. It is a stack. one part of that stack is the base-emitter junction (Vbe). the other part of that stack is the base-collector junction (Vbc). Add them together and you have the total stack voltage (Vce), or Vce=Vbe+Vbc From Equation 4—3, VBE 0.7 V. Calculate the base, collector, and emitter currents as follows: VBE 5 V — 0.7 V 430 lc = ßoclB = = 64.5 mA = 64.5 mA + 430gA = 64.9 mA Solve for VCE and VCB. VCE = Vcc ICRC = 10 V = lov 6.45 v = 3.55v = = 3.55V 0.7 V = 2.85 V Since the collector is at a higher voltage than the base, the collector-base junction i VCE = VCB + VBE for an NPN transistor. VCE = VEB + VBC for an PNP transistor. Ebers Moll Model equations of a Transistor. Ebers and Moll created a model between the current and voltages in the transistor terminals . This model, known as the Ebers Moll model sets the following general equations, for an NPN transistor: IES and ICS represent saturation current for emitter and collector junctions.

The use of terms VCC and VBB means you have a circuit with bipolar transistors. A bipolar transistor is a three terminal device in which the base current controls the current that flows through the collector and emitter. So lets take an NPN transistor and set the emitter to ground in a ten volt circuit The is a basic DC analysis question for a common-emitter amplifier configuration. Two values can be determined by inspection: [math]V_{BE} = 0.7 V [/math], since the forward-biased base emitter junction behaves as a pn-junction diode. [math]V_{CC}..

Below is an NPN transistor characteristics for Vbe versus Ic at different Vcb or Vce: It seems like in the active region, Vbe vs Ic curves gets steeper with an increasing Vce.

Simulate IC as a function of VCE for several VBE values. VBE is from 0.65 to 0.7V, in step of 0.01V. VCE is from 0 to 3V, in step of 0.001V. Note VCE sweep is primary, i.e. the first source to be swept. Indicate the forward bias region and saturation region on the IC-VCE output plot. Your circuit should look like this: Figure 24: schematic for simulating forced-VBE (or voltage drive) output.

Therefore, the Vcb is constant and equal to the difference between Vce and Vbe: VCE-VBE=VCB It was difficult to take exact measures because the resolution of potentiometer was small.
