Title: Tejasvi Anand: Innovator in Low-Voltage Energy Solutions
Introduction
Tejasvi Anand is a prominent inventor based in Corvallis, OR (US). He has made significant contributions to the field of low-voltage energy harvesting, holding a total of 4 patents. His work focuses on developing integrated circuits that enhance energy efficiency and performance in various applications.
Latest Patents
One of his latest patents is an integrated circuit for low-voltage thermoelectric energy harvesting with self-start capabilities. This innovative IC lowers the start-up voltage to approximately 50 mV, making it compatible for initiating a DC-DC converter from a thermoelectric generator (TEG), even with minimal temperature gradients. The IC enhances the end-to-end efficiency of the energy harvester by improving the power efficiency of the DC-DC converter while ensuring maximum power transfer from the TEG at low voltages. It utilizes a low voltage integrated charge pump that can boost sub-100 mV input voltage. Additionally, a startup clock is generated by a ring-oscillator that operates with low supply, allowing for a single inductor to be used for both the DC-DC converter and its startup. This IC can be configured between the TEG and any downstream sensor or communication circuits to provide a sufficient voltage for powering these circuits from a low-voltage TEG energy source.
Another notable patent involves ultra-low voltage circuits. This invention includes an ultra-low voltage inverter that consists of a first inverter, a second inverter, and a third inverter. The first inverter receives input from a delay cell and generates an output for a subsequent delay cell. The second and third inverters are coupled to the first inverter, with their outputs connected to the source terminals of a p-type transistor and an n-type transistor of the first inverter, respectively. This ultra-low voltage inverter forms a delay cell, which serves as a fundamental building block of an ultra-low voltage ring-oscillator. A NAND gate is constructed using three inverters, where the outputs of two inverters are connected to the p-type transistors of the NAND gate, while the output of the third inverter is linked to an n-type transistor of the NAND gate.
