Abstract

A Single Input Dual Output (SIDO) wide input range piezoelectric energy harvester is proposed. A low drop out semi-active rectifier is implemented. The system extracts energy from vibrations whose rectified output voltage ranges from 100mV to 1.65V and a single inductor buck-boost converter is implemented to cater this dynamic wide input range. Maximum Power Extraction from the source is accomplished by hill climbing algorithm and the system operates in dual mode: regulate and dump modes to regulate a 1V load and charge a 1.8V battery respectively. Complete system is implemented in UMC 180nm CMOS technology.
