This paper presents a 60 mV input voltage start-up system for thermoelectric energy harvesting. A new process tolerant inverter cell is proposed, which is functional at supply voltages as low as 60 mV. Using the proposed unit cell, a ring <br/>oscillator has been implemented. The ring oscillator is followed by 40 charge-pump stages, an ultra...

The continuous improvement in reducing the power consumption of electronic devices, including biomedical ones, makes the use of energy harvesting systems instead of batteries attractive. Conventionally, energy harvesting systems are optimized to operate in a single worst-case scenario. However, it is often the case that the available input power...

This paper presents the system and circuit design of a compact radio frequency (RF)-powered 2.4-GHz CMOS transmitter (TX) to be used for autonomous wireless sensor nodes (WSNs). The proposed TX utilizes the received dedicated RF signal for both energy harvesting as well as frequency synthesis. A TX RF carrier is derived from the received RF...

Some systems like RF energy harvesters have power transfer efficiency as one of the most important specifications. Therefore, the efficiency of the matching network, which affects the entire system’s efficiency, plays an important role. When the impedance transformation factor between the antenna and its load is high, the matching network...
