Minus sign (−)(-)(−)
A=VoutVinA = \frac{V_{out}}{V_{in}}A=VinVout
No feedback and very high gain
Output fed back to input
Vout=AOL(V+−V−)V_{out} = A_{OL}(V_{+} - V_{-})Vout=AOL(V+−V−)
No current drawn from input sources
Output stays at supply voltage limit
Positive supply voltage
Resistance increases, VoutV_{out}Vout rises
