It is usually assumed that the l/f noise in Si-MOSFETs is limited by collision l/f noise. We found this to be the case for devices with relatively short channel lengths (L<lOpn) but for channels of intermediate length (10pm<L<194pm) we found that the Hooge parameter varies as L2. We attributed this to acceleration of the electrons by the applied field, accompanied by Bremsstrahlung emission and current l/f noise generation. This is a new noise source.
