In this thesis, three low-noise active mixing circuits are presented in CMOS technology. Mixers can be found at the front-end of almost every communication systems. However, despite many advantages the active mixers have, ...

This thesis explores the design and applications of subharmonic mixers in CMOS microwave integrated circuits. First, a 2x down-converting subharmonic mixer is demonstrated with a measured conversion gain of 8 dB using a ...
