this link is for triangular wave generation using opamp. they provides a circuit file for wave generation n also the circuit diagram. How can i know abt the opamp model they r using for the simulation.. can u guys help !!!
No, the model does not reflect the properties of any commercial part.
It is just a simple behavioural description of some of the most important opamp parameters (gain with one pole, input/output impedance, supply rail limitations).
