<P>PROBLEM TO BE SOLVED: To provide an amplifier circuit capable of raising the common-mode signal rejection ratio and the maximum output voltage while reducing the current consumed and the circuitry scale. <P>SOLUTION: At a stage subsequent to an input differential pair comprising transistors M1 and M2, an output differential pair comprising transistors M3 and M4 having the same polarity as the input differential pair is provided. The source of the transistor M1 is connected to the source of the transistor M3, the source of the transistor M2 is connected to the source of the transistor M4, the drain of the transistor M1 is connected to the gate of the transistor M3, and the drain of the transistor M2 is connected to the gate of the transistor M4. <P>COPYRIGHT: (C)2012,JPO&INPIT |
