Mixers are essential part of the RF ReceiversIn this thesis , different receiver architectures are presentedThe Low - IF architecture proves better performance in terms of integratability , image rejection adaptivity , and flexibility for different standards gilbert - Cell and the passive switching mixers are selected to be studied in terms of conversion gain , linearity , and noise performanceA complete mathematical model for these characteristics is represented mixers are time - varying circuits and time - varying power series for distortion calculation is considered and noise has a time - varying statistics as wellHigh - frequency noise model is accounted for by considering the gate - induced noise dominant at high frequencies
