3. WHAT IS BIAS DESIGN? Bias Design is the reverse process of analyzing a circuit In Analysis of the circuit we find Voltages and Currents In Design we find the values of External Resistors which will produce the necessary bias point

4. STANDARD RESISTANCE VALUES 10, 11, 12, 13, 15, 16, 18 20, 22, 24, 27 30, 33, 36, 39 43, 47 51, 56 62, 68 75 82 91 Other values are obtained by multiplying these values with powers of ten For example 4.7 K Ω is obtained by multiplying 47 to 100 (10 2 )
