Hi all,
I am designing a operational amplifier and using negative feedback in my application,
So V1=V2=Constant voltage, the input voltage is fixed most of the time.
Since input is fixed, I can control the OP consuming current by adjusting input MOS. Can I remove current reference stage as type (B).
Comparing the type A and B, what's the advantage and disadvantage and consideration ?
Thanks in advance
