Beyond 60GHz – CMOS Circuits and Techniques for More Bandwidth, Power and Efficiency

May 30, 2014
2:00-3:00pm
Location: 414 CEPSR
Speaker: Dr. Eran Socher, Senior Lecturer, Tel Aviv University
Host: Harish Krishnaswamy

Abstract

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 poses a major challenge 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 a 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. Examples of measured devices working up to 340 GHz and data rates of up to 20 GBps will be presented.
