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 …
What is the value of Vbb in the circuit given below?
Jan 18, 2017 · A bipolar transistor looks like a diode between B and E to the rest of the circuit. For a ordinary silicon transistor, that is usually 550 to 750 mV or so, depending on current and …
Why should Vbb not exceed the barrier potential values?
Oct 13, 2018 · The voltage VBE across the forward-biased junction is very low (for a germanium transistor, VBE = 0.3 V; and for silicon transistor, VBE = 0.7 V). This requires that the battery …
Vb and Vbe of a transitor - Electrical Engineering Stack Exchange
Sep 23, 2023 · Stack Exchange Network. Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the largest, most trusted online community for …
Interfacing an LVDS driver with an LVPECL receiver
Aug 1, 2017 · VBB = 2V. After the transmission line, the AC coupling caps remove the DC common mode of the driver so that Voh = 0.2V and Vol = -0.2V, correct? I assume VBB sets …
How can I calculate a transistor's IB, VBB and VEE from the given ...
Jun 11, 2024 · \$\begingroup\$ Steam, unless you have already selected a very specific NPN model (and all associated models that relate to it, such as the saturation current model over …
Why is a DC base voltage needed to attain faithful amplification?
Nov 4, 2014 · Vbb is normally called Vbe. Unless Vbe is positive there will be no collector current. (for an npn) Simple models assume a transistor is a current controlled device, but the next …
digital logic - What is the meaning of Vtt - Electrical Engineering ...
Vbb - reference voltage for ECL used in single-ended input mode or for some types of termination. Usually you bypass to Vcc and tie the differential input that's not being used to Vbb, or tie …
Why is the collector voltage must be bigger than the base voltage …
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.
transistors - On a BJT, is there a relationship between the base ...
Aug 23, 2022 · Why do we still have a collector current when Vbb < 5.7 V. Because a saturated switch requires on/off base drive. It's not some comparator circuit that detects when you're …
