Thesis (Ph.D.)

Includes bibliographical references

This thesis presents the design and implementation of digital millimeter-wave transmitters, in silicon, in the 20--140-GHz frequency range. I/Q RF-DAC transmitter architectures with unary-weighted antenna segments and binary-weighted transistor segments are explored to generate high-order QAM modulation formats, while operating in deep saturation and without resorting to upconversion.

520 $a This thesis presents the design and implementation of digital millimeter-wave transmitters, in silicon, in the 20--140-GHz frequency range. I/Q RF-DAC transmitter architectures with unary-weighted antenna segments and binary-weighted transistor segments are explored to generate high-order QAM modulation formats, while operating in deep saturation and without resorting to upconversion.
520 $a The antenna segmentation approach is proven experimentally at 100 GHz with a pair of on-die I/Q driven antenna elements, in a 45-nm SOI CMOS process. The proof-of-concept circuit has an EIRP of 15.7 dBm and a data rate of up to 10 Gb/s. Novel modulator topologies based on the Gilbert cell are proposed to improve the modulation rate and accuracy of digital mm-wave transmitters. These topologies are verified at 90 GHz and at 138 GHz through the implementation of I/Q RF power-DAC transmitters with binary-weighted transistor segments. The 90-GHz implementation results in 19 dBm of output power and modulation rates up to 15 Gbaud. At 138 GHz, a 12-bit I/Q RF power-DAC with on-die antennas is fabricated to demonstrate direct 64-QAM and OFDM modulation of a mm-wave carrier without upconversion. The 138-GHz transmitter has an EIRP of 13.2 dBm and is able to operate at data rates of up to 12 Gb/s.
520 $a Next, techniques to extend the bandwidth and voltage swing of nanoscale CMOS inverter topologies, with resistive and inductive feedback, selective differential-mode inductive peaking, and series stacking are analyzed. These techniques are demonstrated for an optical front-end at 60 Gb/s, with record 4.3-Vpp single-ended output swing, in a 28-nm FD-SOI CMOS process, as well as for two RF-DAC-based radio transmitters at 1--32 GHz with data rates of 20--30-Gb/s, in a 45-nm SOI CMOS process.
520 $a Lastly, mm-wave signal sources and frequency dividers are designed and experimentally verified at 60 GHz and at 240 GHz in a 45-nm SOI CMOS process and in a 55-nm SiGe BiCMOS process, respectively. At 60 GHz, both fundamental and second-harmonic signal sources for low power applications are demonstrated and compared. At 240 GHz, meanwhile, a second-harmonic source with record 7.2-dBm output power and 1-GHz divided-down output is demonstrated.
