As the EB junction is forward biased the holes from emitter region flow towards the base

We know that IC = IB + (1+) ICBO where ICBO is the reverse saturation current. As the
temperature increases ICBO increases there by increase in IC and hence changing the Qpoint.

In the process of manufacturing the transistors different
This d.c. voltage is called bias voltage.
As the input circuit has low resistance, a small change in the signal voltage Vi causes a
large change in the base current thereby causing the same change in collector current
(because IC = IB).
The collector curr

Fig 3.5: p-n-p transistor operated in Cut-off region
When both EB junction and CB junction are reverse biased, the transistor is said to be
operated in cut-off region. In this region, the current in the transistor is very small and
