Hello, I am trying to design my own CE Amplifier using BJT. I am having issues with fixing the Q-Point.
Biasing can be performed in two ways:
So, Which of the above two approach is correct ? Based on what parameter should we bias the base ? Base Current or Base Voltage?
Also, Kindly point me for any resource, that explains selection of base , Collector and emitter resistances.
Biasing can be performed in two ways:
(1)
Ib = (12 - 0.7) / 1k
Assuming, Vbe as 0.7V.
(2)
2.
Here, we are fixing base voltage using voltage divider. (This voltage divider can be made equalent to (1) using thevinin transformation).
