    Hi,
    I'm a bit confused how to write the Laplace transform for a circuit. I want to draw the bode plot of a flyback converter's transfer function using LTSpice's laplace thingy, but not sure how to do that. Say I've got an equation for one of the circuits pole's, the output filter pole. 1/(pi*Ro*Co). So i solve for that and find out the pole occurs at 100Hz. What is the laplace equation for that, 1/(s+100)? The bode plot dont look right.
    Thanks.
