Hello,
I'm designing a two stage opmap. From the specification, the DC gain should be 100db and unity gain bandwidth should be 1GHz. I was trying to implement it with Folded cascode first stage and miller compensation between the two stages. I'm not able to achieve the specified bandwidth. All I could reach was near to 250MHz with a gain of around 97db.
Can you guys please help me here?
Will miller compensation work for higher bandwidth designs or should I go for different type of compensation?
