Abstract :
Mixers are analysed as a linear periodic time-varying (LPTV) system with large LO signal excitation and without small-signal excitation. Efficient simulation of the mixed-signal substrate coupling is possible using macromodels of RF circuits. The substrate noise is added as a small signal disturbance via a coupling contact. A technique using a simple and systematic engineering approach to analyse the impact of the substrate coupling in a mixed-signal RF CMOS mixer is presented
