  "textContent": "A radio frequency to direct current (RF-DC) converter for energy harvesting includes a first cross-coupled circuit and a second cross-coupled circuit. The first cross-coupled circuit includes a pair of NMOS transistors and a pair of PMOS transistors. The second cross-coupled circuit is connected to an output of the first cross-coupled circuit and includes four cross-coupled PMOS transistors. Each of the NMOS transistors and PMOS transistors are fabricated on a substrate using n-well process. An RF voltage source is connected to the RF-DC converter to which an antenna and balun device are connected. An output circuit is connected the second cross-coupled circuit. Multiple stages identical to the second cross-coupled circuit including only PMOS transistors may be added between the output of the second cross-coupled circuit and the output circuit for greater amplification of the harvested energy.",
