Hi !
I want to design an op-amp with the following properties :
- open-loop gain = 10,000 (minimum)
- input impedance = 100 kilo ohm (minimum)
- output impedance = 1 kilo ohm (maximum)
- Vout = 0 for V+ (non-inverting input) = V- (inverting input)
( power supplies must be +/- 6 volt )
actually this is my final project for " principles of electronics " . I've designed following circuit which satisfies first , second and third condition , but I have no idea about fourth .
could anybody help me how to satisfy the fourth condition ?
( I've checked uA741 ( one of the most successful op-amps ) , it doesn't have this property ! )
