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

Obtaining sufficient EVM in all four 1.76GHz bandwidth chann1.76GHzels specified by IEEE 802.15.3c and the emerging 802.11ad high-data-rate wireless communication standards for modulations as complex as QAM16 is a challenge. Recently reported implementations are therefore restricted to just 1 or 2 channels. Wireless applications often use digital low-power (LP) CMOS technology to implement single-chip transceivers. The high V
_t
and the thin metal interconnect layers constrain the mm-Wave circuit performance. This paper presents a digital LP 40nm CMOS 60GHz transceiver (TRX) IC that obtains an EVM better than -17dB in all 4 channels.
