1. The problem statement, all variables and given/known data I need to find the transfer function of the attached circuit (this isn't a homework question so I don't know if there's even a solution, but last time I posted this type of question on the EE forum, it was redirected here) 2. Relevant equations I know it needs to be eventually of the form Vo/Vin and I know how to solve for Vo but I can't seem to get it as Vo/Vin. If it isn't possible, how would one describe this circuit's transfer function? Z1=R1 Z2=R2+1/(s*C) 3. The attempt at a solution Vo=(Z2/Z1)(5V-Vin)+5V Vin is the measured signal from the output of a buck converter and 5V is the reference signal, if that helps at all. The closest I've somewhat gotten is (Vo-5)/(5-Vin)=Z2/Z1 Thanks in advance for all the help!
