Abstract
Consumer electronics are ubiquitous -- in cars, in phones, in smart homes, in everything. This huge, multi-billion-dollar industry continually pushes the technological cutting edge to offer more performance at lower cost to improve our quality of life. Cutting edge techniques and transmitter architectures drive the innovation in the circuit design field today. Furthermore in the age of smart homes, ubiquitous connectivity, and internet of things, the push to make everything connected wireless includes the need for wireless powering. This wireless power delivery shares mathematical similarities to optimum data transmission through a channel. The desire to continuously increase the data rate and the bandwidth and throughput leave engineers with the unique challenge to develop the techniques and radio transmitter architectures of the future. This work summarizes work done to explore two techniques for integrated circuits spanning the entire transmitter chain from mixed signal baseband to RF. The first part discusses a self-calibration algorithm embedded in the digital control of a Digital-to-Analog Converter (DAC) that automatically calibrates for process mismatch which can significantly reduce the contribution of the DAC to the transmit error vector magnitude. The next technique discusses a phase-shifting amplifier (PSA) which is used to generate high phase resolution tunability while also providing gain. The PSA uses techniques inspired from distributed amplification and with proper alignment of phase delays along transmission lines, the signal can obtain the desired phase shift. This segues nicely into projects in the medical field where 60GHz has been a hot research topic. This work also presents the source design optimization problem for a planar tissue model for wireless powering of medical implants. This regime is different from the traditional near-field and far-field transmission regimes and is known as mid-field.
