Describe the disadvantage of the direct-coupling technique.
What will be an ideal response?
A drawback of direct-coupled amplifiers is that they are not stable. Any change in the output current of the first stage is amplified by the second stage. This occurs because the second stage is essentially biased by the first stage. To improve the stability requires the use of expensive precision components.
