Startup Circiut

Hello everyone, I am trying to design a startup circuit to boost up a low input voltage. I want to connect this startup circuit to DC-DC Boost Converter. I only focus on simulation method by using MATLAB/SIMULINK.

I have tried to design boost converter using MATLAB/SIMULINK, but I am worried that I am not understand on how to design startup circuit using MATLAB/SIMULINK.

Can anyone help me? Thanks.

The attach file is my project flow and boost converter's design using MATLAB/SIMULINK.

The attach file is a paper related to startup circuit for DC-DC Boost Converter.

Notice how these "Professors" on give vague descriptions of what they are trying to relate. No actual circuits and even the photograph has no associated details. These people are ALL TALK. They never produce anything.

You can buy a DC to DC converter that goes down to 0.9v for a few dollars on eBay.
