Abstract: Ultra deep submicron CMOS has reached a speed that allows handling of mm-wave signals and in addition, it allows to make digital circuitry very compact. For example, 1 mm^2 can contain 1 million gates in 45nm CMOS. These advantages can be exploited to design complex single-chip transceivers operating at 60 GHz, where a 7 GHz band is available for high-datarate applications. In the coming years we will see several applications operating around 60 GHz, such as wireless HDMI, short-range sync&go and wireless docking stations.
To compensate the high path loss of wireless transmission at 60 GHz, one can make use of phased antenna arrays, which can be made compact at those high frequencies. The use of phased arrays requires electronic beam steering. The elaboration of beamforming architectures in CMOS transceivers together with the design of mm-wave building blocks and very wideband analog baseband circuits is the subject of intensive research nowadays. This presentation discusses the design of mm-wave transceivers in ultra deep submicron CMOS for high datarate mm-wave wireless applications. The design of complete architectures will be discussed, together with the design of individual building blocks such beamforming circuits, frequency synthesizers and classical transceiver functions operating around 60 GHz.
