op amp design HELP
I have to design Differential input (Vin-&Vin+) operational amplifier with input
I bias for external biasing, input SelectExtbias and single ended output.
With the following specs:
OLDC Gain>75db
Unity gain Bandwidth>100Mhz
Phase-Margin>45db
Input referred offset <4mV
Power Supply Rejection at 1 KHz >40db
Input range: 0.5V<Vin<1.5v
Output range: 0.5V<Vout<1.5v
Vdd=2.5V =+/-25%
Iref External 10uA+/-20%
Slew Rate (unloaded)>100V/us
Does anybody know how I will start?
Thanks
