TL;DR: In this paper, an apparatus having both a resonator and an inductor fabricated on a single substrate and a method of fabricating the apparatus is described. But the method of fabrication is not described.
Abstract: An apparatus having both a resonator and an inductor fabricated on a single substrate and a method of fabricating the apparatus are disclosed. The apparatus includes a resonator and an inductor that is connected to the resonator. Both the resonator and the inductor are fabricated over their respective cavities to produce a high Q-factor filter circuit.

TL;DR: In this paper, a thin-film inductor and power IC are integrated in a monolithic DC-DC converter, and the authors describe the micro DCDC converter module utilizing this IC.
Abstract: In this paper, we report the newly developed DC-DC converter IC termed monolithic DC-DC converter, in which a thin-film inductor and power IC are integrated, and describe the micro DC-DC converter module utilizing this IC. The thin-film inductor used in the monolithic DC-DC converter was fabricated by RF sputtering, photosensitive polyimide lithography and electro-plating onto the power IC. The micro DC-DC converter module using the monolithic DC-DC converter achieved power density of 5.6 W/cm/sup 3/ at output power of 1 W and maximum efficiency of 83.3% at switching frequency of 3 MHz.

TL;DR: This paper presents the analysis of open-loop power-stage dynamics relevant to current-mode control for a boost pulsewidth-modulated (PWM) dc-dc converter operating in continuous-conduction mode (CCM).
Abstract: This paper presents the analysis of open-loop power-stage dynamics relevant to current-mode control for a boost pulsewidth-modulated (PWM) dc-dc converter operating in continuous-conduction mode (CCM). The transfer functions from input voltage to inductor current, from duty cycle to inductor current, and from output current to inductor current are derived. The delay from the MOSFET gate drive to the duty cycle is modeled using a first-order Pade/spl acute/ approximation. The derivations are performed using an averaged linear small-signal circuit model of the boost converter for CCM. The transfer functions can be used in modeling the complete boost PWM converter when current-mode control is used. The theory was in excellent agreement with the experimental results, enforcing the validity of the transfer functions derived.

TL;DR: This paper proposes a comprehensive modeling for single-phase qZS-PV inverter system with a real PV source is established and discussed without and with a PV terminal capacitor, and the system parameter design method is proposed to mitigate this ripple.
Abstract: The second harmonic $(2\omega)$ power ripple of single-phase quasi-Z-source (qZS) photovoltaic (PV) inverter highly affects the whole system's design and performance. The topology's $2\omega$ ripple model is very important to analyze qZS PV inverter's $2\omega$ voltage and current ripple. The existing models did not consider the PV-panel dynamic and terminal capacitors, which causes the theoretical results apart from the truth. In this paper, a comprehensive modeling for single-phase qZS-PV inverter is proposed, where the $2\omega$ ripple model of the qZS-PV inverter system with a real PV source is established and discussed without and with a PV terminal capacitor. The influences from qZS inductance and capacitance, and PV-panel terminal capacitance to the $2\omega$ voltage and current ripple are investigated using the built model. The system parameter design method is proposed to mitigate this ripple. Simulation and experimental results validate the proposed $2\omega$ ripple model and parameter design method.

TL;DR: In this paper, a class of protruding rocket antennas of low silhouette is analyzed in terms of an approximately equivalent circuit that consists of a shunt-driven transmission line terminated in a reactor at each end.
Abstract: A class of protruding rocket antennas of low silhouette is analyzed in terms of an approximately equivalent circuit that consists of a shunt-driven transmission line terminated in a reactor at each end. Expressions for the currents in the several parts of the circuit are used to determine the Poynting vector and from this the radiation resistance referred to the current in the generator. The reactance is obtained from transmission-line formulas.
