I'm very confused, how does sensor size have anything to do with DoF (depth of field)? Depth of field means how much is in focus and it's a function of the aperture of the lens. I think what you mean is the sensor changes the effective focal length: a 50mm lens on FF is 50mm, on a Canon crop factor it gets a 1.6x multiplier, on Nikon I think it is 1.5x (sorry, haven't shot Nikon since film).
