Multistage transistor Amplifier
A transistor circuit containing more than one stage of
amplification is known as multistage transistor amplifier. In this amplifier a
number of single amplifier stages are connected in cascade arrangement. Cascading
means the output of first stage is connected to the input of the second stage through
a suitable coupling device and son on. The coupling devices are generally
capacitors, transformers etc. the purpose of coupling device is.
1. To transfer a.c. output of one stage,
to input of the next stage.
