* Question
| What is the main source of BJT (bipolar triode) noise? |
* Answer
| There are three main types of noise in BJT:
(1) Thermal noise: due to the irregular thermal motion of the carrier passing through the bulk resistance in the BJT.Expression: In2=2Qib (3) Flicker noise: Also called 1/f noise, the current cause is not very clear, and it is related to the semiconductor itself and the process level. |
