Minimum select circuit!

Hello every one,

I am designing the circuit to chose the minimum. What is best way to do it? Thank alot!
 

Re: Minimum select circuit!

Minimum current?
 

Re: Minimum select circuit!

No. That is minimum voltage.
 

Minimum select circuit!

You can do it by two diode. connect anodes through a resistor to the +Vcc supply. And use each cathode as a input. If you want to eliminate diode voltage drop, use buffer amplifier.
