With 60 GHz CMOS circuits going into products and devices that keep scaling, CMOS can now operate at 100 GHz and beyond. However, operating near or above the transistor ft/fmax and the dominant parasitics pose major challenges for traditional circuit topologies. In this talk several techniques for generating and detecting signals at short millimeter wave frequencies with high output power, wide bandwidth and high efficiency will be discussed, including variations on the Colpitts oscillator, the use of harmonics and multi-band architectures. Interfacing the chip at these frequencies through on-chip antennas and transitions will also be discussed, as well as new opportunities that arise with these interfaces, such as better efficiency, wider bandwidth and integrated energy harvesting. Examples of measured CMOS chips working up to 625 GHz and data rates of up to 20 Gbps will be presented.
