Single Stage Ce Amplifier Circuit Diagram. Specification bias circuit design for the single stage common emitter amplifier circuit in shown in fig. The voltage divider biasing has a potential divider with two resistors are connected in a way that the midpoint is used for supplying base bias.

For splitting the signal you can use resistors for basic splitting. The different circuit elements and their functions are described as follows. This technique used to isolate the dc bias settings of the two coupled circuits.

The resistances r 1 r 2 and r e form the biasing and stabilization circuit.

This type of biasing arrangement uses two resistors as a potential divider network across the supply with their center point supplying the required base bias voltage to the transistor. Connect the circuit diagram as in the one marked with amplifier with gain 20 and you get 20 fold the signal. The single stage common emitter amplifier circuit shown above uses what is commonly called voltage divider biasing. Current and voltage phase shift of 180 0.
