Have to assume it also provides a reasonable non-linear approximation (but have yet to verify this). Can confirm the PDK does not seem to model noise correctly, as the numbers come out unrealistic (which was a possibility according to the response).</P><P><SPAN style="font-size: 10.0pt; font-family: 'Arial',sans-serif; mso-fareast-font-family: 'Times New Roman'; color: black; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;">AFT05MS003N_PDK can be used to predict operational performance at +5V drain voltage.
