Description: Energy harvesting from natural ambient like solar, thermal and vibrational transducer has emerged as a promising solution to tackle power supply challenges in miniaturized devices such as wireless sensor node, biomedical implants etc. We aim to design a fully on chip energy harvesting system for wearable and portable devices using charge pump, thus eliminating the need for off chip inductor. In this work, energy is scavenged from single transducer (solar/thermal) at very low voltage (150-450 mV). The system involves a simple feed forward MPPT unit, battery management and power management unit along with an independent cold start up circuit to trigger system from zero charge condition. Contributions Design of charge pump based DC-DC converter for energy harvesting from solar and thermal transducers. Design of sensor circuit to detect the environmental conditions, so as to turn on and turn off the power converter element for power saving. Design of battery management unit to protect battery from under voltage as well as over voltage. Also, it facilitates to turn on startup circuit when battery voltage drains out. This design has been successfully Taped out in UMC 180 nm technology. Cadence Virtuoso has been used as the tool for entire design flow. The GDSII has been sent to the EUROPRACTICE IC Services offered by IMEC for fabrication. Software Used Cadence Virtuoso, Analog Design Environment 180nm technology Course Projects Power efficient reconfigurable charge pump for micro scale energy harvesting. A charge pump with high voltage step up ratio is essential to boost the voltage from tiny transducer as well as to charge an energy buffer for storage. Conventional Linear and Fibonacci charge pumps have better current deriving capabilities at higher and lower voltage ranges, respectively. So we design reconfigurable charge pump topology which can utilize merits of both Linear and Fibonacci charge pumps for wide range of input voltage. Low complexity algorithm for linear system solver This project mainly aims at exploring the symmetry potential of determinant computation based on the conventional approach of cofactor expansion of determinant calculation. SRAM Memory Design 256x64 SRAM cell design using 65nm technology considering the parasitic effect of wires using RC delay modeling in Cadence Virtuoso to analyze timing for read and write operation of critical path.
