23Gbps 9.4pJ/bit 80/100GHz band CMOS transceiver with on-board antenna for short-range communication

Abstract

Fully integrated 80GHz-band and 100GHz-band transceiver ICs using 65nm CMOS technology and on-board antennas for high-speed/short-range wireless communication system are demonstrated. To realize higher speed and lower power consumption than those of a 60GHz-band standard application such as IEEE802.11ad, a simple transceiver architecture with non-coherent amplitude shift keying (ASK) modulation method using W-band (75-110GHz) is adopted. The aggregate 80/100GHz-band transceiver modules demonstrate 23Gbps over 10mm wirelessly with power consumption of 216mW. The developed transceiver modules achieve the highest speed of wireless communications above 60GHz-band and show a potential for future applications of 100Gbps high-speed shortrange communications.

15-Gb/s 50-cm Wireless Link Using a High-Power Compact III–V 84-GHz Transmitter

“…The distance between the transmit and receive horn antennas was 50 cm. The 2 15 -1 PRBS (pseudo-random binary sequence) data from Keysight M8040A is superimposed through bias-T on DC bias of the RTD transmitter. The corresponding modulated output is transmitted through the on-wafer RF probe terminated with horn antenna (Tx).…”

“…[13] [14], for instance, 60 GHz carrier frequencies using 90 nm CMOS are demonstrated using OOK modulation with corresponding 3.3 Gbps/10.7 Gbps data rates over 4 cm/10 cm ranges. In [15], 80/100 GHz transceiver using 65 nm CMOS is demonstrated using ASK modulation at 23 Gbps over a 1 cm wireless link. In [16], a 57/80 GHz transceiver using 40 nm CMOS shows ASK modulated 20 Gbps over a 5 mm wireless Table I.…”

A 90-98 GHz CMOS Transmitter Frontend for Concurrent Phase-Coded FMCW Radar Applications

“…The millimeter-wave spectrum is attractive for various applications as it allows high resolution radars [1]- [4] and high data rates [5], [6] due to the wavelength-resolution relation and high relative bandwidth, respectively. The ongoing scaling of CMOS transistors along with the increasing f T enable fully integrated systems on a single die and, in addition, 94 GHz offers low atmospheric attenuation.…”

15 Gbps Wireless Link Using W-band Resonant Tunnelling Diode Transmitter

“…The modulation scheme employed was amplitude shift keying (ASK), which has the advantages of simple implementation, low cost modulation/demodulation process and high bandwidth efficiency, etc. Compared with many standard CMOS techniques [3]- [5], the RTD transmitter design in the paper does not require any power amplifier (PA) or frequency multiplier/synthesizer stage, which greatly reduces the circuitry complexity and design costs. Besides low DC power consumption, the proposed transmitter is promising for future low-cost high speed wireless communication links.…”
