Capacitively-Coupled Bridge Readout Circuits
This Ph.D. dissertation describes the design and realization of energy efficient readout integrated circuits (ROICs), that have an input referred noise density < 5 nV/√Hz and a linearity of < 30 ppm, as required by Wheatstone bridge sensors used in precision mechatronic systems. Novel techniques were developed, at both the system-level and circuit-level, to improve the ROIC’s energy-efficiency, while preserving its stability and precision. Two prototypes are presented, each with best-in-class energy efficiency, to demonstrate the effectiveness of the proposed techniques.

3D Elements for Phased-Array Systems: Analysis and Design.
Phased arrays for radar and communication systems require supporting frequency and angular selectivity functions to reduce interference and enable more flexible operation. Frequency selective surfaces with large rejection bands and their integration with phased arrays are investigated. Moreover, array of tilted dipole elements are proposed to achieve radiation with asymmetric field of view.
