ABSTRACT:
A semiconductor integrated circuit device is comprised of an amplifier circuit having first and second PMOS and NMOS transistors. The first PMOS transistor has a gate electrode and a drain electrode connected together. The second PMOS transistor has a gate electrode connected to the gate electrode of the first PMOS transistor and a course electrode connected to a course electrode of the first PMOS transistor. The first NMOS transistor has a drain electrode connected to the drain electrode of the first PMOS transistor and a gate electrode sat as a first input terminal. The second NMOS transistor has a drain electrode connected to a drain electrode of the second PMOS transistor, a source electrode connected to a sourse electrode of the first NMOS transistor, and a gate electrode sat as a second input terminal. At least one of the first NMOS transistor and the second NMOS transistor is comprised of a buried channel transistor.
