Hello,
I'm trying to simulate an ultra-low voltage amplifier from ALD company, but I can't find the parameters required for the simulation in ADS or Qucsstudio. Despite thoroughly reading the datasheet, I was unable to find the specific information I need. My voltage supply for the simulation is set at 0.25 V. I wonder if someone has used ALD110800/ALD110900 for simulation in ADS or if anyone has the SPICE model of those transistors. The circuit that I'm trying to simulate is this:
I tried using JFET transistors and injected a sinusoidal signal with an amplitude of 10 mV. However, I obtained an output of 10e-4 V with an offset of 0.135 V. I'm not sure why this is happening. In my simulation, I used U1 and U2 as P-type transistors.

Hello! Thank you very much for your help!
I may have another question. I simulated my circuit with an input voltage of 30 µV and a supply voltage of 0.25 V. However, at the output of my system, I'm getting an amplified signal with an offset. I want to know where this offset is coming from and if it's normal to have it, or if my circuit is not functioning properly.
Here is my input and output signals
