A differential RF-DC CMOS converter for RF energy scavenging based on a reconfigurable voltage rectifier topology is presented.

Abstract
A differential RF-DC CMOS converter for RF energy scavenging based on a reconfigurable voltage rectifier topology is presented. The converter efficiency and sensitivity are optimized thanks to the proposed reconfigurable architecture. Prototypes realized in 130nm provide a regulated output voltage of ~2V when working at 868MHz, with a -21dBm sensitivity. The circuit efficiency peaks at 60%, remaining above the 40% for a 18dB input power range.File | Dimensione | Formato | |
