Abstract: PROBLEM TO BE SOLVED: To reduce variations in amplification factors due to the dispersion of mutual conductance of an FET and distortion due to nonlinearity between an input and an output of the FET. SOLUTION: The amplifier comprises two FETs 41 and 42. A resistor Rf is connected between the source of the FET 41 and the source of the FET 42. The source of the FET 41 is grounded via a resistor 45. A load resistor 48 is connected between the drain of the FET 41 and the drain of the FET 42. A DC power supply is connected between the drain of the FET 41 and the ground. A first signal voltage E1 is applied between the gate of the FET 41 and the ground. A second signal voltage E2 is applied between the gate of the FET 42 and the ground.
