A Fully Integrated 60-GHz CMOS Transceiver Chipset Based on WiGig/IEEE 802.11ad With Built-In Self Calibration for Mobile Usage

Abstract

This paper presents a fully integrated transceiver chipset based on the WiGig/IEEE 802.11ad standard targeting mobile usage. The chipset is developed for single-carrier (SC) modulation, which is suitable for reduced power consumption. However, the SC modulation is sensitive to in-band amplitude variations, mainly made worse by the gain variations of analog circuits and multipath delay spread. In order to compensate for these gain variations, the proposed chipset employs built-in TX in-band calibration and an RX frequency domain equalizer (FDE). The proposed techniques relax the requirement for high speed analog circuits, leading to less power consumption while minimizing the increase of hardware size. The test chip achieves 1.8 Gb/s MAC throughput for up to 40 cm and 1.5 Gb/s for up to 1 m while consuming 788 mW in TX and 984 mW in RX mode.
