Voltage Gain Amplifier Topology

RIN, ROUT, AV

Applied to BJT (CE) Amp Need for BJT (Common Collector) Amp

o System Level Thinking (Block Diagram) o Specifications: RIN, ROUT, AV o Ideal Values / Definitions o Applied to the BJT (CE) Amp o Small-Signal (ac) Analysis o Evaluation – How good is the BJT (CE) Amp? o Need for Multi-Stage Amplifiers o BJT Common Collector (Emitter Follower) o Most Common Output Stage - the Push-Pull Pair
