This paper presents a 60-GHz CMOS transceiver designed for IEEE 802.11ay. To reduce the manufacturing cost, an area-efficient bi-directional technique is utilized in this work. The proposed bi-directional amplifier allows the sharing of interstage passive components. A 5-stage PA-LNA designed based on the proposed bidirectional amplifier occupies less than half on-chip area, while staying a similar performance with the conventional standalone PA and LNA. Considering the MIMO configuration, this work integrates two transceiver elements in the same chip. Thanks to the area-efficient bidirectional circuits, the transceiver in this work only requires 0.96-mm2 core area including the quadrature up- and down-conversion. The occupied core area for a 5-stage PA-LNA is 0.44mm2. The measured noise figure for the proposed transceiver in RX mode is 5.4 dB at 60 GHz. The measured TX-mode EVM is -26 dB in 64-QAM with an output power of -4.2 dBm. This work realizes a maximum data rate of 28.16 Gb/s in 16-QAM. A 64-QAM two-channel-bonding data rate of 21.12 Gb/s is also achieved by the transceiver with a -22.5-dB TX-to-RX EVM. The power consumptions are 94 mW in TX mode and 105 mW in RX mode. |
