ADS and Credence results do not match ?!

Hello guys,

I have designed an LNA in ADS with tsmc 180nm and I got appropriate results. However, when I simulate exactly the same circuit with same parameters and components i get different result in cadence ! It is so awkward I do not know how can I fix this !

Anybody has an idea ?!?!?

Most likely the two simulators use different models for the same part...

I used tsmc 180 for both. All models are from that library

Which simulator do you use ? Small Signal or Large Signal ?

I do ADE L and sp simualtion

S-parameters simulations must be very close.If there is some discrepancies between the simulators, there is probably either a simulation setup error or model faults.Cadence ADE setup for a PDK needs sometimes few tricks to simulate the circuits properly.Take this into account..
