Question

Design a universal bias for class -A CE-amplifier using NPN transistor for the following parameters values;Vcc=20V, Vв=4V, Iс=10mA, Vве=0.6V,Vсе=10V and β=100.Obtain the values of Rс,Rе,R₁ and R₂

Answer 1

See the diagram for common emitter configuration of npn transistor, in a Universal biasing circuit.

We will not worry about the capacitors. We will worry about the DC biasing and the resistors RL, RE, R1 and R2.

Given Ic = 10 mA
Assuming the transistor has a current amplification factor  = β = 100.
So IB = base current ≈ Ic / β = 10 mA /50 = 0.2 mA.
