20.4 A fully integrated single-chip 60GHz CMOS transceiver with scalable power consumption for proximity wireless communication

A 7.6 mW 2 Gb/s Proximity Transmitter for Smartphone-Mirrored Display Applications

“…As discussed in Part I, the inductive coupling based transceiver [9] achieves lowest power consumption with 1.1 Gb/s data rate, however 1 mm coupling range can hardly support good user experience for the proposed smartphone mirrored applications. Including some digital baseband, the 60 GHz transceiver [3] consumes 580 mW at 2 Gb/s data rate, which is not suitable for the smartphone-based applications. Compared to the work in [6,13] which are based on the UWB technology, this work achieves the highest data rate with the highest energy efficiency.…”

“…Proximity transceivers [3][4][5][6] are promising for this kind of applications since it can achieve relatively high energy efficiency and a very short range provides secure wireless transmission. However the 60 GHz radio based on the IEEE 802.11ad standard exhibits a few Gb/s data rate [3,4] but suffers from high power consumption at the peak data rate, causing a potential problem of high heat index to the human skin.…”

Coherent ultra-wideband (UWB) transceivers have difficulty in achieving high energy efficiency for >500 Mb/s data rate [5][6][7][8].…”

Research on CMOS mm-wave circuits and systems for wireless communications

“…The 60GHz transceiver has received significant attention as an enabler for multi-Gb/s point-to-point wireless communication [28][29][30][31], but conventional approaches with digital baseband processors and high-speed digitizers highly increase the design complexity and power consumption, in addition to the integration difficulty. In [13], a fully-integrated CMOS 60 GHz transceiver with 5 GHz RX/ dB variable gain range.…”
