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(More)
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(More)

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(More)
