Abstract :
A simple linear periodic time-varying circuit model is proposed to rigorously analyzed the noise behavior in active mixers. Explicit formulas for thermal noise folding factor and flicker noise leakage are derived. Based upon our analysis, mixers operating at the off overlap mode are shown to provide better noise performance. The analysis is validated against simulations and measurements
