Abstract |
|
This paper proposes an RF to DC power converter for ambient wireless powering that is efficient, highly sensitive and less dependent on load resistance with an extended dynamic range. The proposed rectifier design is fabricated using a 90nm standard CMOS technology. The designs of rectifiers are discussed and the double entered rectifier topology chosen was simulated using Ansoft Nexxim designer. The energy harvesting circuit module includes an impedance matching circuit to avoid loss of energy derived by the antenna unit to achieve maximum power conversion efficiency (PCE) and sensitivity. The measured result achieved 99.9% power conversion efficiency (PCE) for below 10 GHz of frequency which almost covers major RF application band source frequencies and can serve for future low-maintenance SoC applications. |
