here is a model..how can i find value of lambda (used in ro=(1 / Id*lambda) )

MOSIS WAFER ACCEPTANCE TESTS

RUN: T8BY VENDOR: AMIS
TECHNOLOGY: SCN05 FEATURE SIZE: 0.5 microns
Run type: SKD


INTRODUCTION: This report contains the lot average results obtained by MOSIS
from measurements of MOSIS test structures on each wafer of
this fabrication lot. SPICE parameters obtained from similar
measurements on a selected wafer are also attached.

U can simulate it easily. LAMDA is the first order model and can be easily extracted out of Ids vs Vds curve of a MOS transistor

if it is possible to get value of lambda from model without stimulation?

Usually there is a parameter LAMDA but I do not see it in your model. That means that the Id equation used by the model is different then text book model. Simulation is your best bet. A simple setup will work
