Amplitude conversion circuit for converting signal amplitude and semiconductor device using the amplitude conversion circuit

An amplitude conversion circuit converting a first signal having an amplitude corresponding to a first voltage into a second signal having an amplitude corresponding to a second voltage higher than said first voltage, comprising:

• first and second transistors of a first conductivity type having respective first electrodes both receiving said second voltage, respective second electrodes connected respectively to first and second output nodes for providing said second signal and a complementary signal of said second signal, and respective input electrodes connected respectively to said second and first output nodes;
• third and fourth transistors of a second conductivity type having respective first electrodes connected respectively to said first and second output nodes;
• and
• a drive circuit driven by said first signal and a complementary signal of said first signal, providing, in response to a leading edge of said complementary signal of said first signal, a third voltage higher than said first voltage between an input electrode and a second electrode of said third transistor to turn on said third transistor, and providing, in response to a leading edge of said first signal corresponding to a trailing edge of said complementary signal of said first signal, said third voltage between an input electrode and a second electrode of said fourth transistor to turn on said fourth transistor.
