  In the scenario of single-field inflation, this field is done in terms of
Jacobian elliptic functions. This approach provides, when constrained to
particular cases, analytic solutions already known in the past, generalizing
them to a bigger family of analytical solutions. The emergent cosmology is
analysed using the Hamilton-Jacobi approach and then, the main results are
contrasted with the recent measurements obtained from the Planck 2015 data.
