Abstract

A semiconductor device detects and adjusts leakage current dependent on threshold voltage of an integrated semiconductor device. To adjust the threshold voltage variation due to uncertainties in the channel length induced by the fabrication process (short channel effect) in the semiconductor a comparison between small and long channel devices is proposed. According to the comparison result, a bias potential is provided to the semiconductor device to adjust the threshold voltage.
