  We investigate two approaches to non minimally coupled gravity theories which
present linear inflation as attractor solution: a) the scalar-tensor theory
approach, where we look for a scalar-tensor theory that would restore results
of linear inflation in the strong coupling limit for any form of the
non-minimal coupling to gravity of the form of $f(\varphi)R/2$; b) the particle
physics approach, where we motivate the form of the Jordan frame potential by
the loop corrections to the inflaton field. In both cases the Jordan frame
potentials are modifications of the induced inflation, but instead of the
Starobinsky attractor they lead to the linear inflation in the strong coupling
limit.
