Hi ,
If any body can explain the working principle of this bgr ckt which is attached. or a general bgr ckt.
I am confused whether at the input of the opamp, one input should be PTAT and other be at CTAT?
Ikept the both inputs varying on the same direction with bell shape when we see volt vs Temp. because we have to sum together thats why if same inputs are given to diff.amp. it will again make difference so , ultimatly we get Sum.
Sincere Thanks
