The ever-increasing demand for higher data rates has been the driving force behind the push for mm-wave frequencies in communication systems. The recently released IEEE 802.15.3d covers a frequency range from 252 to 325 GHz, which offers an even larger bandwidth than the previously explored D-band frequencies. A 16nm process possesses extra challenges on the design of circuits above 200 GHz, especially as we get closer to the fmax of the process, and it is largely unexplored due to the degraded RF performance compared to the planar CMOS technologies while offering the unique benefit of integration with very high-performance mixed signal and digital circuits.
This seminar presents a set of Transmit (TX) and Receive (RX) chipsets for J-band (252-325 GHz) communication, implemented in 16-nm FinFET CMOS. Both systems are designed to utilize amplitude-shift-keying (ASK) modulation and to operate non-coherently, alleviating the need for a synchronized LO between TX and RX. Both chips are characterized standalone in a probe station. The seminar will also touch on some challenges in the RF design using the 16nm node.
