Abstract :
This paper presents a 64-QAM 60GHz CMOS transceiver, which achieves a TX-to-RX EVM of -26.3dB and can transmit 10.56Gb/s in all four channels defined in IEEE802.11ad/WiGig. By using a 4-bonded channel, 28.16Gb/s can be transmitted in 16QAM. The front-end consumes 251mW and 220mW from a 1.2-V supply in transmitting and receiving mode, respectively. Figure 20.3.1 shows the 60GHz direct-conversion front-end design. The transmitter consists of a 6-stage PA, differential preamplifiers, I/Q passive mixers and a quadrature injection-locked oscillator (QILO). The receiver consists of a 4-stage LNA, differential amplifiers, I/Q double-balanced mixers, a QILO, and baseband amplifiers. A direct-conversion architecture is employed for both TX and RX because of wide-bandwidth capability [1]. The LO consists of the 60GHz QILO and a 20GHz PLL. The 60GHz QILO works as a frequency tripler with the integrated 20GHz PLL. It can generate 7 carrier frequencies with a 36/40MHz reference, 58.32GHz(ch.1), 60.48GHz(ch.2), 62.64GHz(ch.3), and 64.80GHz(ch.4) defined in IEEE802.11ad/WiGig, 59.40GHz(ch.1-2), 61.56GHz(ch.2-3), and 63.72GHz(ch.3-4) for the channel bonding.
