    Hi, I'm trying to simulate this circuit in PSpice but I only get constants out whereas I should get something sinusodial.
    The circuit:

    I have found Vt = g(Vi,V0):

    And here is the Schematic, I really do not know how to make anything else than plain contants. Can anyone help please? Have I made the integrator wrong?

    Thanks.
