Abstract

Ambient Radio Frequency (RF) energy harvesting has been an attractive area of research due to its eventual applications in many modern low-power systems. The RF waves are present on several high frequency and at low power (a few μW). We present in this paper a new architecture RF-DC rectifier circuit operates at dual simultaneous frequencies. The bands frequencies chosen for this work are GSM (900MHz) and WIFI (2.45GHz). The proposed rectifier is designed in three stages using the MOSFET transistors, the capacitors and the inductors. The technology used is CMOS 0,18μm from TSMC and the simulations were performed using the ADS (Advanced Design System) Simulator. This circuit provides a Power Conversion Efficiency (PCE) of 68.4 % with an input power Pin= -21.3 dbm and an output voltage Vout=1.67 V for the frequency 900 MHz and a PCE of 72.4 % with an input power Pin= -20.5 dbm and an output voltage Vout=1.7 V for the frequency 2.45GHz.
