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.
In the original paper, the author's input is as low as several mV. I'm curious about how to do it. If you are interested, I put the paper below.Thank you very much
