An amplification circuit may include an input differential pair including a first transistor receiving a positive input voltage and a second transistor receiving a negative input voltage, a first resistor that generates a difference current corresponding to a difference voltage between the positive input voltage and the negative input voltage, an output differential pair including a third transistor supplying a negative output voltage and a fourth transistor supplying a positive output voltage, a second resistor connected to a reference voltage to receive the difference current generated by the first resistor, and a bias circuit that supplies a bias current to the first transistor, the second transistor, the third transistor, and the fourth transistor. The first transistor, the second transistor, the third transistor, and the fourth transistor may have the same polarity.
