The input capacitor Cin ( Coupling Capacitor) used to couples AC input signal voltage to the base of the transistor and it blocks the DC from the previous stage.Ī step-down transformer provided with a suitable turn ratio to couple the high impedance collector to a low impedance load. The emitter bypass capacitor CE and emitter resistor Re are connected parallel to prevent AC voltage. The circuit has the potential divider resistors R1 & R2, biasing and emitter bypass resistor Re, used for circuit stabilization.
