In order to provide a semiconductor device having a means for operating normally even when the amplitude of a signal voltage is smaller than the amplitude of a power source voltage, a correcting means is provided before a digital circuit to be operated normally. As for a signal outputted from the correcting...http://www.google.de/patents/US20040257117?utm_source=gb-gplus-sharePatent US20040257117 - Semiconductor device and display appliance using the semiconductor device
