Hi !
I'm trying to re simulate the Deferentially-Fed rectifier proposed in https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=7096951
"an enhanced rectenna using differentially-fed rectifier for wireless power transmission"
I need to find the RF-DC conversion efficiency but i do not know what the equation is.
I have simulated the single-fed rectifier and gotten correct results but i do not know how to manage having two P_1tone's. What would the input power be in this case?
Thanks in advance :smile:
 

P_PROBE is a ground referenced power probe. It can't measure DC output power in this circuit.

Simply add another P_Probe to opposite side of load resistor, if you would like to measure power delivered to load by P_Probe.
 

thank you for your reply.
How can i measure the DC power output then ?
 

Hi! if i add another P_probe on the opposite side of the load, do i keep P_probe1? and what would my efficiency equation be?
