A low-power 57-to-66GHz transceiver in 40nm LP CMOS with -17dB EVM at 7Gb/s

A direct-conversion transceiver in 40nm digital LP CMOS for 57-66GHz wireless communication is described. In TX mode the IC consumes 185mW with 10.2dBm P1dB. In RX mode consumption is 130mW with a NF of 5.5dB and 30dB gain. The frequency generation uses a subharmonically injection-locked QVCO with 8GHz locking range over the 57-66GHz band. ESD robustness is more than 4kV HBM. The transceiver achieves -17dB EVM for QAM16 modulation in the 4 channels specified by IEEE 802.15.3c standard.
