Who can talk about power amplifier based on CMOS tech?

Recently, I will develop the power amplifier based on CMOS tech, but I don't know much about its disadvantages? if somebody would like to talk about it, thanks a lot.

Mosfet...?,PWM or Switcher should be in thought.

In my designs, low power and high supply voltage is fit for PWM,and low supply and more power may be switcher's field.
