I am a newbie in the design of opamps would like to know your opinion. This is an inverting amplifier with Av = -(R2/R1)
1) The gain depends on R2 and R1 , just what are the factors influence the accuracy of it?
2) What is the load resistor role why is it connected to the non -inverting terminal
3) What kind of topology? can we use NMOS 2 stage OTA?

Please let me know
