PROBLEM TO BE SOLVED: To provide a level shift circuit which has a sufficient amplitude conversion ability even when the voltage amplitude of an input signal is small, uses less power, and operates at a high speed. SOLUTION: With respect to n-channel MOS transistors TN-A and TN-B and p-channel MOS transistors TP-A and TP-B comprising the level shift circuit, p-channel MOS transistors TP-C and TP-D comprising a current mirror circuit are formed at the drain of the p-channel MOS transistors TP-A and TP-B. In this manner, the level shift circuit is provided which prevents through-current from VDDH to VSS and operates at a high speed. COPYRIGHT: (C)2006,JPO&NCIPI
