A 120GHz fully integrated 10Gb/s wireless transmitter with on-chip antenna in 45nm low power CMOS

In this paper a fully integrated D-band transmitter with on-chip dipole bondwire antenna implemented in 45nm low power CMOS is presented. On-chip frequency generation, insensitive to VCO pulling, is integrated together with a direct carrier quadrature vector modulator, ASK modulator, 4-stage differential transformer-coupled power amplifier and antenna. Digital baseband circuits are also integrated on the same chip. The chip is capable of generating QPSK and Star-QAM modulation formats. Data transmission over a distance up to 1m is achieved for data rates as high as 2Gb/s. For shorter distances, data rates up to 10Gb/s are measured.
