Abstract Details

During the last decade, the advances in digital signal processing together with CMOS radio frequency integration have led to development of direct digital radio frequency circuits. Nevertheless, the operating speed in the early designs doesn't meet the new specifications of the current communication standards. Recently, modern communication systems have handled a tremendous amount of digital data at multiple frequency ranges in what is referred to as multi-carrier applications. This increase the demand for a wideband high speed transmitter that can handle more data bandwidth while meeting the needs for spectral efficient modulation schemes. Also, with the growth in the transistor integration, multi-carrier transmitters have been the best candidate for modern communication systems. However, because this occurs at very high speed, shifting the data from digital domain to the analog domain is becoming very challenging. This dictates a requirement for transmitters capable of wideband, complex waveform modulation, as well as for highly integrated, miniaturized power-efficient solutions.\\ In this Thesis, a novel arbitrary waveform generator (AWG) is proposed to address these needs with a solution that is realized within an integrated circuit (IC). By overcoming the challenges associated with the implementation of the AWG in an IC, he proposed solution is able to effectively address the wide range of needs described above For any transmitter to support this wide range of frequencies and higher data rates, a wideband high speed digital to analog converter (DAC) is needed, as the transmitter effective bandwidth is determined by the DAC band width. The proposed AWG is equipped with a 14-bit high-speed DAC that offers high-resolution amplitude modulation (AM) and operates up to a rate of 30 GHz. Adding to that, the AWG is uniquely equipped with a phase/timing modulation (PM) capability of sub-picosecond timing resolution and operates at a rate up to 15 GHz in this mode. Moreover, different calibration methods have been proposed to mitigate amplitude, time, and phase error inside the design. The AWG system is fabricated in a 45nm CMOS SOI process to verify the simulated results.
