My tired 11 week old refuses to sleep or nap

Mila
Help! I don't know what to do.
My baby boy, refuses to sleep or nap. He is tired,he yawns and rubs his eyes but cries bloddy murder when we are trying to get him to sleep. He falls asleep while drinking his bottle but wakes up as soon as we burp him or when the bottle is out. He doesn't want a pacifier (which i'm ok with), and when he does fall asleep in my arms we cannot lay him in his bed, and i can't sit down either because he wakes up. 
We have checked he does not have colic, or gaz, his diaper is not wet and he is not hungry. 
Any ideas on how to get him to stop fighting sleep?
