Energy Harvesting PMIC Design for an Extended Power-Range

This work proposes an energy harvesting DC-DC converter that is able to efficiently process a wide input power range from 25 mW up to 250 mW, to charge a storage device used in Internet-of-Things (IoT) applications. An interleaved boost-converter topology with two inductors is used to divide the high currents over the two branches, in order to...

Single-Channel Heterogeneous-Source Energy Harvesting PMIC Design

This work proposes an energy harvesting platform that is able to convert power from both DC sources (photo-voltaic cells and TEGs) as well as piezo element sources. It does so only using a single input channel to which a single harvester can be connected. The proposed system is able to differentiate between the two source...

A Low-Complexity CMOS Receiver for UWB signals

It is well-known that GPS is a widely used technology for localization in outdoors environments. Nonetheless, such standard fails to provide a practical and accurate solution for localization and ranging applications within indoor environments due to the need of satellites and meter-level accuracy, which is poor for indoor environments. It is in...

A CMOS Temperature Compensated Log-Amp Detector

Publications of bipolar log-amp detectors for RF power detection show good temperature and RF performance. So far published CMOS log-amps fail to demonstrate accurate performance over temperature. This thesis present a temperature compensated CMOS RF power detector based on the log-amp architecture with an industry temperature range of -40 C to...

Design of a fully integrated CMOS highly temperature stable frequency reference

A new fully integrated frequency reference has been designed, fabricated and measured. The goal of the design procedure has been high stability of the frequency over temperature variations. This should be achieved using a CMOS technology without MEMS and crystals, while being restricted by a very low power budget. The frequency is designed based...
