The present invention is switched with a high gain linearity relates to a capacitor variable gain amplifier, according to the present invention, it is possible to sampling phase and to share the sampling capacitor in the amplification phase to reduce the voltage gain error due to capacitor mismatch by using, there is an effect capable of using the unit capacitor arrangement simplifies the design and layout of the circuit. Further, according to the present invention, can be controlled simply with less than one or one or more of the voltage gain according to the needs, it can be relatively power consumption by a large feedback factor and reduce kT / C noise and improves gain amplifier with there is in effect. Variable gain amplifiers, switched-capacitor feedback factor, the unit capacitor array
