Abstract :
This paper proposes differential design techniques for W-band CMOS applications. Transformers are used as passive matching circuits, which provide numerous advantages compared to traditional matching circuits. Stabilization and gain improvement of the differential pair is achieved by a wideband neutralization technique. These techniques are combined in a fully differential amplifier which is successfully measured. To our knowledge, this is the first fully differential 100 GHz CMOS amplifier.
