Hello, I'm learning about the Royer oscillator. Through a paper on IEEE, I got the following circuit topology. This is an oscillator that can start oscillation at very low input voltage( a non isolated push full boost converter). In order to better understand the structure of the circuit, I try to reproduce the circuit in the paper, but unfortunately, the circuit can not run.what is wrong?I'm not sure if I can upload the paper so here are the attach file and the circuit diagram. Thank you very much
The Royer as front end of a push-pull converter can give you a turns-ratio boost in voltage but so could a self-oscillating flyback or boost converter. A possible issue with the Royer is that taking power.off the secondary might kill the cycle (like, at startup, what does the shorted winding do to the "tank"?). Sometimes you are better off separating the singing from the dancing.
Sorry, I put the original paper in the attachment.The author replaced the MOS of the traditional Royer oscillator with JFET, so that the circuit can be boosted under extremely low input conditions. I simulated the circuit in the original text (the author also used LTSPICE), but I could not get the results in the paper, which made me very confused

Hello, thank you for your reply. I am interested in environmental energy harvesting, especially the boost circuit without external control system. this paper can boost the voltage under several mV conditions, If you are also interested, you can see the file below, Thank you.
