A new method is proposed that defines the possible impedance regions that are guaranteed to produce linearly independent system of equations required for accurate noise parameter extraction. The results show the proposed regions produce noise parameter solutions within 3uncertainties of noise parameters found with patterns previously reported in literature but with the minimum of only four impedances. Additionally, a model to characterize the non-linear noise of a Gilbert Cell mixer in terms of multiple sets of noise parameters was successfully implemented using a system of non-linear equations. A measurement procedure was designed to extract the parameters in the non-linear model in order to solve for the multiple sets of noise parameters. The maximum error between measured and modeled noise factors was less than 3% at any impedance.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
