Patrice Garcia2, Sorin P. Voinigescu1 1 University of Toronto, Toronto, Canada, 2STMicroelectronics, Crolles, France Recently, several integrated radio receivers and transmitters operating at 60GHz have been developed in SiGe BiCMOS [1] and CMOS [2-4] technologies, by both industry and academia. As CMOS transistor gate lengths continue to scale downward, integration becomes possible at even higher frequencies. This paper presents a fully integrated receiver, with LNA, mixer, IF amplifier, fundamental-frequency quadrature VCO, and static frequency divider, operating at 95GHz in a 65nm general-purpose (GP) CMOS technology. The receiver consumes 206mW from a 1.2V/1.5V supply. With large RF and IF bandwidths of over 19GHz and 16GHz, respectively, it is suitable for passive-imaging applications, and for wireless chip-to-chip communication at data-rates exceeding 20Gb/s. Together with the recently reported 60GHz
