Transformer Coupled Amplifier Diagram. Transformer coupled amplifier working can be explained as follows. When the base section of the initial transistor receives alternating current signal then the transistor amplifies the signal and the amplified signal is observed at the transistors collector section where it has a connection with the primary transformer.

Transformer coupled amplifier working can be explained as follows. Transformer coupled transistor amplifier. As we have already discussed in our previous tutorial in case of a rc coupled transistor amplifier the voltage and power gain are low since the effective load resistance of each stage is decreased due to the low resistance presented by the input of each stage to the next stage.

R1 r2 resistors provide the biasing and stabilization for the circuit.

Transformer coupled amplifier working can be explained as follows. Cin isolates dc and allows only ac components from the input signal to the circuit. The potential divider network r 1 and r 2 and the resistor r e together form the biasing and stabilization network. The emitter capacitor provides a low reactance path to the signal and offers stability to the circuit.
