CMOS logic integrated circuit

摘要

A CMOS logic integrated circuit includes a level shifter and a CMOS logic circuit. The level shifter converts a signal of a first logic level to a signal of a second logic level. The signal of the first logic level changes between a first low potential and a first high potential higher than the first low potential. The signal of the second logic level changes between the first low potential and a second high potential higher than the first high potential. The CMOS logic circuit includes a first N-channel type MOSFET and a second N-channel type MOSFET. The second N-channel type MOSFET is connected in series with the first N-channel type MOSFET. A first signal of the first logic level is input into a gate of the first N-channel type MOSFET. A second signal of the second logic level has an inversion relationship with the first signal.
