This paper presents 64-quadrature amplitude modulation (QAM) 60-GHz CMOS transceivers with four-channel bonding capability, which can be categorized into a one-stream transceiver and a two-stream frequency-interleaved (FI) transceiver. The transceivers are both fabricated in a standard 65-nm CMOS technology. For the proposed one-stream transceiver, the TX-to-RX error vector magnitude (EVM) is less...
A novel high-data-rate low-power spectrum-efficient 60GHz Bi-Phase-On-Off-Keying (BPOOK) transceiver is presented for indoor short-range IoT application targeting the common 60GHz spectrum mask used in IEEE 802.11ad/ WiGig standards. By employing bi-phase encoder and double-balanced mixer, the BPOOK transmitter spectrum is efficient to be compliant with 2-channel bonding spectrum mask. The proposed...
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,...
A low-power and small-area 60-GHz CMOS transmitter with oscillator pulling mitigation is presented. The subharmonic injection locking technique for the suppression of pulling effects is analyzed and demonstrated. The transmitter fabricated in a 65nm CMOS process achieves 7.04-Gb/s data rate with an EVM performance of −25 dB in 16QAM. The whole transmitter consumes 210 mW from a 1.2-V supply and occupies...
It is predicted that the required wireless communication capacity will become 1000 times higher every 10 years. Many wireless standards are under discussion to satisfy the unprecedented capacity requirement. For example, the IEEE802.11ay standard is targeting over 100Gb/s data-rate by using the 60GHz band. Unfortunately, the channel bandwidth of 2.16GHz for the 60GHz band is not wide enough to realize...
Dense wavelength-division multiplexing (DWDM) is a promising technique to increase capacity of nanophotonic interconnects for chip-scale serial links. This paper describes recent progress in DWDM nanophotonic interconnects based on silicon microring resonators, including a five-channel DWDM transmitter using a quantum dot (QD) comb laser and carrier-injection modulators, as well as self-adaptive CMOS...
The research of 60GHz CMOS transceivers has bloomed due to their capability of achieving low-cost multi-Gb/s short-range wireless communications [1]. Considering practical use of the 60GHz CMOS transceivers, longer operation lifetime with high output power is preferred to provide reliable products. Unfortunately, as indicated in [2], the output power capability of the transmitter will gradually degrade...
An area-efficient 60-GHz wake-up receiver (WuRx) using reconfiguration techniques of multistage low-noise amplifiers (LNAs) is presented. The gain stages of the 60-GHz LNA are reused as the envelope detectors for the wake-up receiver. Therefore, the bulky components such as extra switches between the wake-up receiver and the LNA, additional antennas, and excess input matching network can be removed...
