To ALL IEEE FOOTHILL SECTION members, here is an opportunity to explore some of the technology developments that will factor into the 5G communication specifications. For the ultra-large bandwidths that will be available at the potential millimeter wave 60 GHz carrier frequency, there will be hardware design needs to have “clean” I / Q modulator devices for the QAM signal modulation. This means that attention will be on phase errors, and resulting amplitude and phase correction circuitry. Consider coming to this meeting, organized by IEEE CLAS Section and open to all out IEE Foothill Section members, for a technical update.

Abstract provided by our presenter, Tian-Wei Huang, Ph.D.
In our daily life, we have smart phones, smart TVs, or even auto-pilot smart cars in the future. In our engineer careers, we have smart antenna, smart baseband chips, but we still need auto-calibration smart RFICs. Especially for millimeter-wave RFICs with giga-hertz bandwidth, the narrow-band baseband calibration cannot compensate the broadband AM/AM or AM/PM non-ideal properties.
For future multi-band multi-standard radio, auto-band-switching is an essential function to optimize RF performance and to simplify the system control interface. A Miller-divider-type frequency sensor can be used to detect the frequency of input signal and perform auto-band-switching inside RFIC without any system control bits. For parametric sensitive 3rd-order nonlinearity, we need parametric-insensitive calibration methods to compensate the non-ideal behavior within RFIC. For millimeter-wave phase array system, the phase error comes from not only phase shifters but also other functional blocks, like variable gain amplifier (VGA), during phase shifting and gain compensation. We need a phase-error calibration method to compensate the phase error from all RFIC blocks.
To optimize system EVM performance, IQ modulator/demodulator are the key components to compensate IQ mismatch at RF frequency, which is also the enabling technology for gigabit high-QAM wireless links. The load-insensitive indicator is used to evaluate different IQ topologies. For IQ self-calibration at RF frequency, the phase compensation has more design challenges than the amplitude calibration, so composite right/left-handed transmission line, switching capacitor array, and phase shifters have been proposed in the IQ phase calibration. All above built-in self-calibration and auto-switching functions are innovated to pave the road to the next-generation millimeter-wave 5G mobile smart RFIC.
Speaker’s Bio:
Tian-Wei Huang (S’91–M’98–SM’02) was born in Taipei, Taiwan, in 1965. He received the B.S. degree in electrical engineering from National Cheng Kung University, Tainan, Taiwan, in 1987, and the M.S. and Ph.D. degrees in electrical engineering from the University of California at Los Angeles (UCLA), in 1990 and 1993, respectively.
In December 1993, he joined TRW (now is Northrop Grumman), where he designed millimeter-wave and microwave GaAs/InP RFICs for satellite applications. From 1998, he was engaged in research on 28-GHz transmitter design and power amplifier packaging for LMDS systems at Lucent Technologies, San Jose, USA. From 1999 to 2002, he was with Cisco Systems, where he developed the high-speed cable modem head-end and Wi-Fi system test.
In August 2002, he joined the faculty of National Taiwan University, Taipei, Taiwan. Prof. Huang was the recipient of IEEE 2009 Transaction on Advanced Packaging Best Paper Award. Currently, he is the TPC member of IEEE RFIC symposium. He is also a voting member of IEEE 802.11 Wi-Fi gigabit wireless standards. His research interests include millimeter-wave RF-CMOS design, and 5G millimeter-wave calibrations.
