The 60GHz carrier with 9GHz bandwidth enables ultra-high-speed wireless communication in recent years [1–4]. To meet the demand from rapidly-increasing data traffic, the IEEE802.11ay standard is one of the most promising candidates aiming for 100Gb/s data-rate. Both higher-order digital modulation such as 128QAM and channel bonding at 60GHz are considered to be used in the IEEE802.11ay standard. However,...
This paper presents a digitally-calibrated 60-GHz direct-conversion transceiver. To improve the error vector magnitude (EVM) performance over the wide bandwidth, a digital calibration technique is applied. The 60-GHz transceiver implemented by 65 nm CMOS achieves the maximum data rates of 20 Gb/s in 16QAM mode. The transmitter and receiver consume 351 mW 238 mW from 1.2V supply, respectively. As a...
This paper presents a 60-GHz direct-conversion transceiver using 60-GHz quadrature oscillators. The 65nm CMOS transceiver realizes the IEEE802.15.3c full-rate wireless communication for every 16QAM/8PSK/QPSK/BPSK mode. The maximum data rates with an antenna built in a package are 8 Gbps in QPSK mode and 11 Gbps in 16QAM mode within a BER of < 10−3. The transceiver consumes 186mW while transmitting,...

This paper presents a 60-GHz direct-conversion transceiver using 60-GHz quadrature oscillators. The transceiver has been fabricated in a standard 65-nm CMOS process. It includes a receiver with a 17.3-dB conversion gain and less than 8.0-dB noise figure, a transmitter with a 18.3-dB conversion gain, a 9.5-dBm output 1 dB compression point, a 10.9-dBm saturation output power and 8.8-% power added efficiency...
This paper presents the design of a sideband-suppressed synthesizer for dual-carrier MB-OFDM transceivers covering 11 frequency bands from 6.2GHz to 9.4GHz and 3 frequency bands from 4.2GHz to 4.8GHz, each with a bandwidth of 264MHz. Careful band plan is made to minimize the complexity. The synthesizer generates 14 carrier frequencies from a single frequency source. Improvements are made to the circuits...
