as shown in the image. i want to use nmos as a switch and using that i want to get different combination of resistances. i will connect Vout to opamp's output(negative feedback).
i tried a lot but i am unable to switch on the NMOS. even i have tried for different W/L ratios.
Vin- : 1.65 V DC and 1 V AC
Gate volatges of NMOS : 0/1.65V DC
ref is connected to inv input of opamp.
Anybody can help me or give me a suggestion? Thank you in advance.
