Question

Which type of biasing is used in CE amplifier?

(a) Fixed bias

(b) Collector to base bias

(c) Voltage divider bias

(d) Emitter bias

I had been asked this question in a job interview.

I need to ask this question from CE Amplifier with an Emitter Resistance topic in chapter Low Frequency Transistor Amplifier Circuit of Electronic Devices & Circuits

Answer 1

Right choice is (c) Voltage divider bias

Easy explanation: The single stage common emitter amplifier uses biasing commonly called “Voltage Divider Biasing”. This type of biasing arrangement uses two resistors as a potential divider network across the supply with their center point supplying the required Base bias voltage to the transistor.
