A modified 0.35 μm gate-length MOSFET large-signal microwave device model, based on the widely used BSIM3 model, is presented in this report. This large-signal microwave model includes a BSIM3 model together with the passive components required to fit the device dc and microwave characteristics over a wide range of biasing points and frequency operation. In this report, we propose a methodology to improve the device microwave linearity by controlling a suitable biasing condition, which is based on the predictions of this modified CMOS large-signal model. The input IM3 enhances more than 10 dB at a 2.4 GHz operation. Furthermore, the adjacent channel power ratio also improves 7.5 dB with proper choosing device dc bias.
