Transformer – Coupled Amplifier
The main drawback of RC coupled amplifier is low voltage and
power gains and poor impedance matching. This is because of the decrease in
effective load RAC of each stage. If the effective load resistance
of each stage could be increased, the voltage and power gain could be
increased. This van be achieved by transformer coupling. Transformer coupling
is generally employed when the load is small. It is mostly used for power
amplification.
