Common Drain Amplifier Circuit Diagram. Two more resistors are also required as drain resistor and source resistor. Calculate the maximum collector current ic flowing through the load resistor when the transistor is switched fully on saturation assume vce 0.
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 voltage. Thus the collector terminal is common to both the input and output circuits. For common drain configuration the circuit diagram in cd fig 1.
This means that the source follower circuit is able to provide excellent performance as a buffer.
This type of configuration is called common collector cc because the collector terminal is effectively. 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 voltage. To serve the purpose a generic voltage divider is constructed using two simple resistors. Note that r d is absent in this case and we have added an isolation resister riso because of the capacitive loading of chi2.
