A novel 60 GHz RF/DC power harvesting system is presented. The system   consists of RF to DC rectifier and a DC/DC Buck converter based on constant   ON/OFF time (COOT) control. The rectifier has a structure of voltage doubler,   but employs diodes that have lower parasitics compared to those of the   standard MOSFET diodes, resulting in improved power conversion efficiency.   The peak efficiency of the rectifier obtained with the extracted parasitics   for the output power of 1 mW is about 25%. In order to keep the output   voltage of the system to 1.2 V, the COOT control in the Buck converter is   used. COOT control has much better efficiency at low output powers compared   to the PWM systems. For correct operation of the COOT control, auxiliary   sub-blocks: a low power high-speed comparator, a hysteresis comparator, and a   high-speed voltage reference are designed and presented. The maximum   switching frequency in the Buck converter is about 100MHz and the whole   control system has very low static power consumption. The efficiency of the   overall system for the output power of 1mW is about 21%. The system is   designed in 65 nm CMOS technology
