Abstract :
Second order nonlinearity of Gilbert mixer is analyzed. The harmonic generations at each part of the mixer are analyzed and are combined to predict the over-all mixer behavior. We include non-ideal tail current source and nonlinear current gain of BJT, which are neglected in previous works but have significant effects.
