Abstract :
The linearity analysis of a passive mixer is presented. The distortion mechanism caused by switching operation of an NMOS transistor is elucidated from the DC analysis of passive mixers. Furthermore, the maximum input level to keep linear operation and its required bias condition is derived. The calculated linearity performances agree well with simulated results.
