Abstract

In this paper, a fully integrated -band transmitter with on-chip dipole bondwire antenna imple mented in 45 nm low-power CMOS is presented. The purpose of this 120 GHz wireless connector is to provide a high-speed short-range wireless communication link. On-chip frequency g eneration, insensitive to VCO pulling, is integrated togeth er with a direct carrier quadra- ture vector modulator, ASK modul ator, four-stage differential transformer-coupled power ampli fier, and bondwire antenna. A -bit PRBS generator, capable of generating three parallel bit streams at a clock frequency of 8 GHz, is integrated on the same chip for measurement purpos es. The transmitter is capable of efficiently generating BPSK, QPSK, and Star-QAM modulation formats. Data transmission over a distance up to 1 m is achieved for data rates as high as 2 Gb/s. For shorter distances, data rates up to 10 Gb/s are measured.
