The three biasing schemes are:

  • Constant-voltage bias, which is most useful for RF and video amplifiers employing small dc drain resistors. Also known as voltage divider bias.
  • Constant-current bias, which is best suited to low-drift dc amplifier applications such as source followers and source-coupled differential pairs. Also known as fixed …
