  We propose that the baryon asymmetry of the Universe may originate from the
amplification of quantum fluctuations of a light complex scalar field during
inflation. CP-violation is sourced by complex mass terms, which are smaller
than the Hubble rate, as well as non-standard kinetic terms. We find that, when
assuming 60 e-folds of inflation, an asymmetry in accordance with observation
can result for models where the energy scale of inflation is of the order of
10^16 GeV. Lower scales may be achieved when assuming substantially larger
amounts of e-folds.
