Advantages and disadvantages of direct coupled amplifier

There are some advantages of direct coupled amplifier which are given below,

  • The direct coupled amplifier has a excellent frequency response.
  • The circuit cost is low because the absence of expensive coupling components.
  • The circuit is very simple because it uses a minimum number of resistors.
  • It can amplify very low frequency signals down to zero frequency.

There are some disadvantages of direct coupled amplifier which are given below,

  • The direct coupled amplifier cannot amplify high frequency signals.
  • Its output is not drifting less.
  • The output changes with the time and change in supply voltage.
  • It has poor temperature stability, due to this its operating point shifts.
  • At low frequencies capacitor fail and act like a short circuit.
