This paper presents 3D IC design of a fully integrated four-phase buck converter. The control circuit was implemented in the TSMC 0.18μm CMOS Mixed Signal RF General Purpose MiM Al 1P6M 1.8 & 3.3V process while the passive components were implemented in the tMt Glass Substrate Integrated Passive Device (IPD) Process, and then these two dies are(More)
BACKGROUND Studies evaluating the role of transbronchial lung biopsy (TBLB) in diagnosing pulmonary tuberculosis (PTB) date back decades and have shaped current practice. However, with the recent advent of bronchoalveolar lavage (BAL) Xpert® MTB/RIF, it is time to re-evaluate the role of TBLB. OBJECTIVE To assess the impact of BAL and TBLB with the(More)
This paper presents a single-inductor multi-output (SIMO) dc-dc converter for gigascale systems, which includes two different kinds of control loops, the comparator loop and the error amplifier (EA) loop. The proposed converter can provide four output voltages with only five power switches, two comparator loops, and two error amplifier loops. To save(More)
