The most accurate current mirrors

It is made of 3 current mirrors(2 PNP, and 1 NPN). It's accuracy is only 1mA(.001 amp) gain at every 30 volts.

Very nice. Whats the best way to modify the output.

Change the nearest resistor to the output which is the 300 ohm resistor to the left of the LED. It really is a combination of all the resistors, and also the transistors modifications, but it's more helpful with that one resistor.

Which type of real transistor do you advice?

How can I change the Max value? With the resistor adjust it only gives about 60mA. I wnt to use 3 Amps...

You can also change the resistors on the left for raising the amperage. You wouldn't really use current mirrors for higher current, I don't know what you would call it, but it's used in the 741 op amp, and voltage regulators. I'll post it.
