Which of the following parameters are affected due to short-channel MOSFET geometry I. Mobility of carriers II. Threshold voltage III. Drain current Correct Answer I, II and III

Short-channel effect in MOSFET:

  • If the channel length of MOSFET becomes comparatively equal to the depletion layer widths of source and drain junction then it is called that MOSFET suffers from short-channel effect.
  • Due to this effect, the following parameters are affected
  • Mobility of charge carrier in the channel
  • The threshold voltage changed due to a shorter length of the channel.
  • Drain current also changed as threshold voltage changed


So, based on the above points all statements are true
