	One of my senior friends told me about this marathon, and at that moment, I was
completely blank. After taking part in this, I don't know what to do, but as Kunal sir take
the first session, I was cleared; I want to do this let's give ourselves a chance to 
explore something new, and later today, at the end of this marathon I found it great 
thank you, everyone, for organizing this.
	I came across the buck-boost converter after reading a research paper on charging 
circuits. I go through a lot of research papers on DC-DC buck-boost converters. I select 
two papers among all of them and start penetrating them. Most things are available on the 
internet, but I realized that the values of components, their formulas, and built 
instruments for this are not available for the Dc-DC buck-boost converter. That part is 
really tough for me and then sky130 models. Circuit designing in Esim generating netlist 
and then converting it to simulate in spice takes a lot. I had faced problems while 
plotting and editing netlist, but it was fun. Mentors from the group truly helped me a lot.
	Sir there was a problem while simulating the designed circuit. The output graph is 
not similar to the reference graph. I really worked hard on how to make it possible. I 
shared my project with Sumanto Sir and Sameer Sir to check it but at the end they said just 
submit the above figure with no option left. Sorry for the inconvenience from my side, but 
i will definitely try to find out how to do that without using mosfet as a switch.
