300GHz CMOS — Can spintronics help?

This talk will give an overview of research on millimetre-wave/THz CMOS circuits at Hiroshima University, which recently culminated in the demonstration of a transmitter capable of a data rate of 105Gbit/s. 300GHz CMOS circuit design is extremely challenging because the MOS transistor’s unity-power-gain frequency, fmax, is below 300GHz. The topics to be covered include millimetre-wave measurements, a little bit of circuit design, and possible applications. Finally, I will discuss possible scenarios in which spintronics could help and vice versa.
