碩士 === 國立臺灣科技大學 === 電機工程系 === 106 === This study focuses on the novel on-chip metamaterial-based self-oscillating active integrated antenna (AIA) using zeroth-order resonator. The active circuit of AIA is performed by using 0.18-μm CMOS technology. Moreover, the antenna part is performed by using the integrated passive device (IPD) process. Two designs are researched and developed in this thesis. First of all, a novel self-oscillating AIA based on zeroth-order resonators is proposed. The connecting line between the gate and the other drain terminals in a cross-coupled pair is broken up to insert a zeroth-order resonator in between. By utilizing the zero-phase-shift property of a zeroth-order resonator, the phase of the feedback loop is zero and the oscillation happens. The oscillation parameters are investigated in details. The size of active circuit is drastically reduced by using 0.18-μm CMOS technology. Secondly, to achieve on-chip metamaterial-based self-oscillating active integrated antenna (AIA), the circuit layout of the previous case is re-investigated to develop another zeroth-order resonator. Different from the former design, in the latter case, the antenna part is performed by using integrated passive device (IPD) instead of PCB process. The first on-chip design of metamaterial-based self-oscillating AIA is by using flip chip technique of National Chip Implementation Center (CIC) to combine the integrated passive device (IPD) process with 0.18-μm CMOS process. The small size makes it full of flexibility and mobility. The chip is in the tape-out stage now, and it will be measured after it is totally completed in the future.
