Abstract: Methods and systems for producing circuitry using stackable passive components are discussed. More specifically, the present disclosure provides designs and fabrication methods for production of stackable devices that may be used as components in circuitry such as filters and impedance matching adaptors. Such components may be used to save space in printed circuit boards. Moreover, stackable passive components may be dual components, which may be improve the electrical performance in certain types of circuits such as matched component filters.

Abstract: The disclosed embodiments provide a system that manages use of a battery in a portable electronic device. During operation, the system operates a charging circuit for converting an input voltage from a power source into a set of output voltages for charging the battery and powering a low-voltage subsystem and a high-voltage subsystem in the portable electronic device. Upon detecting the input voltage from the power source and a low-voltage state in the battery during operation of the charging circuit, the system uses a first inductor group in the charging circuit to down-convert the input voltage to a target voltage of the battery that is lower than a voltage requirement of the high-voltage subsystem. The system also uses a second inductor group in the charging circuit to up-convert the target voltage to power the high-voltage subsystem.

Abstract: Systems and methods described in this disclosure are related to fabrication and utilization of two-terminal electrical components that may have terminations with reduced width. Components, such as the ones described herein may be used to increase the density of components in electrical devices, as they may reduce a separation distance between devices that lead to solder bridging. Methods for fabrication are also described, including the use of ceramic layers that may provide reduction in parasitic capacitance and/or inductances.
