Dear Ansys users<\/p>\n

Hope this post find you well, and I thank you all in advance for your reaction.<\/p>\n

I used simplorer to buid the following circuit, where the voltage input is as it shown in red curve ( Vop and Vom are the positive and negative pin for the input) , Vbp and Vbm are also the positive and the negative pins of power supply DC 5+ Volts.<\/p>\n

Measuring Vpp to ground  shoud give -10 to 10 V …. yet this is noot working.<\/p>\n

What I think is the problem is that my input voltage offset is not zero and I tried to make it a zero without success and it change the value each time I run the simulation, and I found that in the amplifier parameters there is a (Input offset) line and I should enter the value so the voltage is to be amplified correctly which is not possible in my case as the offset change the value each time I run the simulation and there is no way to predict the value.<\/p>\n

Can anyone identify  where I am mistaken? any suggestions are of a great apreciation.<\/p>\n
