Back calculating the input from output signal chain with an isolated amplifier and opamp
The culprit here was the input impedance of AMC1350.It's value is 1.25 MΩ (typ).
To solve this I reduced the value of resistors present in the voltage divider network.
Please see the circuit below.
N …

PMOS Saturation Condition
we know for nmos works in active region, we must have Vgs-Vth>0 and Vds>Vgs-Vth.
For PMOS can I write like this | Vgs|-|Vth|>0 , |Vds|>|Vgs|-|Vth|.
Please correct me if I am wrong
