i wanna design dc operational amplifier,which includes:
Internally frequency compensated for unity gain
Large dc voltage gain 100dB
Wide bandwidth (unity gain) 1MHz
Wide power supply range 0→5v
Very low supply current drain(500ua)-essentially in dependent of supply voltage
Low input offset voltage 2mv
Input common-mode voltage range includes ground
Differential input voltage range equal to the power supply voltage
Large output voltage swing 0v to Vdd-1.5v
anyone who offer some circuit structure or opam document to me,thanks!
best regard!
ithink
you can use any evolutionary algorithms to design analog and digital circuit.
GA is one of evolutionary algorithms. but i offer you to use DE (diffrential evolutionary) it has very fast conversion.
in this method just you give your schematic to CAD and your problem and it design your circuit.(it computes R, C , L, W/L and others)
for more information search in google "design+analog circuit+GA"
