Fixed bias (base bias):
Diagram: Fixed bias (Base bias)
This type of biasing is also known as base bias. In the instance above figure, the single power source (for instance, a battery) is employed for both collector and base of transistor, even though separate batteries can as well be used.
In the given circuit,
Vcc = IBRB + Vbe
Hence,
IB = (Vcc - Vbe)/RB
For a specific transistor, Vbe does not change significantly during use. Since Vce is of fixed value, on selection of RB, the base current IB is fixed. Hence this kind is termed as fixed bias type of circuit.
As well for given circuit,
Vcc = ICRC + Vce
Vce = Vcc - ICRC
The common-emitter current gain of a transistor is a significant parameter in circuit design, and is fixed on the data sheet for a particular transistor. It is represents as β on this page.
Because
IC = βIB
We can acquire IC as well. In this way, operating point given as (Vce,IC) can be set for specific transistor.
