This thesis presents a series of options for enhancing the implementation of arbitrary-phase spread spectrum waveforms, a highly-secure class of wireless technologies, in order to reduce design complexity with minimal loss, provide methods for real-time performance adaptations, and extend the traditional application space for increased security of communications in other networks. A number of enhanced hardware prototypes were implemented to provide measurable results, achieving substantial computational resource gains and design flexibility. Given the computational resources and power constraints of devices in the Internet of Things (IoT), the signal detection loss of 2.10 dB for reducing the hardware logic utilization of the brute force fallthrough correlator by more than 76% (and eliminating the need to dedicate computationally-expensive embedded multipliers) is a very reasonable trade. While the waveform is fundamentally designed for increased security, adapting to widespread and/or commercial use may allow some sacrifice of the signal’s ability to avoid interception/detection to improve performance in undesirable operating conditions. In a similar, yet reversed, case, injecting a watermarking signature at the physical layer (PHY) of less-secure wireless technologies for receiver-side authentication also proves to be beneficial.

The spurious-free dynamic range of RF DAC's are limited by the heavy digital do- main switching, which interferes with the analog output signal. A design, layout and simulation of a spread-spectrum clock generator (SSCG) is presented. The SSCG modulates the clock frequency used to switch the digital blocks of the DAC in order to reduce electromagnetic interference (EMI) spurs at the analog output signal of the DAC. Leveraging on a phase control architecture rather than a traditional PLL, the SSCG system is shown to reduce the spectral height a divided down clock spur up to 19.6dB. The SSCG is designed in TSMC's 65nm CMOS process. It takes in quadrature, differential clocks at either 2.5GHz or 5GHz, and provides quadrature output clocks at 625MHz or 1.25GHz. The output spectrum of the clock can be attenuated up to 19.6dB relative to the spectrum of an unspread clock. The core of the SSCG is a phase interpolator, which takes in quadrature input clocks and interpolates between them to move the frequency around. To help process the signals before and after interpolation, the SSCG incorporates input variable gain lters, output restoration buffers and divide by 4 circuits. Extensive transistor and behavioral simulations are used to verify the design.
