CMOS RF Modeling and Parameter Extraction Approaches Taking Charge Conservation into Account
نویسندگان
چکیده
A charge conserving small-signal equivalent circuit with very simple and accurate parameter extraction method for a three-terminal CMOS RF model is presented. We found that significant errors in circuit performances can be obtained if charge conserving non-reciprocal capacitances are not properly considered. It is also found that one accurate large-signal I-V model is enough to be used for DC, low-frequency analog, as well as RF circuit simulation

A novel extraction method of high frequency small-signal model parameters for MOSFET is proposed. From S-parameter measurement, this technique accurately extracts the MOSFET model parameters including the charge conservation capacitance parameters. To consider charge conservation, nonreciprocal capacitance is considered. The modeled S-parameters fit the measured ones well without any optimizati...
