Hello I am unable to simulate AC analsis for the attached circuit , Please help me out.
The low pass filter connected to the Instrumentation amplifier has cutoff frequency of 40Hz

Hello Jayarama,
The issue has to do with TINATI considering C3 as floating. To overcome this you can either delete C3 and probe at the output of the opamp or attach a resistive load to ground in between C3 and VF1.
