ABSTRACT:
The present invention discloses an amplifier which can amplify signals based on a specific amplification factor at high speed without inhibiting electrical characteristics. A first switch 22 is connected in parallel with a third resistor 10. A second switch 24 is incorporated into an operational amplifier 6 between the inverted input and the noninverted input. A switch controlling means 26 regulates the switching of the first switch 22 and the second switch 24. When the second capacitor 14 is charged to obtain the reference voltage V.sub.REF, the switch controlling means 26 closes the first switch 22 and the second switch 24.
