MOSFET channel resistance characterization from the triode region to impact ionization region with the inductive breakdown network
Examine RF impact ionization with different Lg using the same CMOS technology node. The extraction of channel resistance should be separated from the breakdown network. Z22 and S21 is influenced by the breakdown network at low frequency as Lg reduces. The power gain at breakdown is lower than the value at saturation due to breakdown.
