UNIT V

UNIT V: Transistor biasing-stabilization and Field Effect Transistor

The DC and AC load lines, Operating point, need for biasing , fixed bias, collector feedback bias, Emitter feedback bias, Collector-Emitter feedback bias, Voltage divider bias - bias stability and stabilization factors, stabilization against variations in VBE and β.

Field Effect Transistor: The Junction field effect Transistor (Construction, Principle of operation, symbol) Pinch – off voltage, V-I characteristics, The JFET small signal model, comparison of BJT and FET (Qualitative treatment).
