Common Emitter vs Common Source Amplifier

Common Emitter Amplifier vs Common Source Amplifier

CE and CS Amplifiers Output Resistance



Observation: For comparable bias points, output resistances of common emitter and common source amplifiers are similar.


BJT and FET Small-Signal parameter Comparison:


The dc I-V Active region expressions used:



CE and CS Amplifiers Summary:


 Amplifier Power Dissipation

Static power dissipation in amplifiers is found from their dc equivalent circuits.
