Abstract: The present invention relates to a variable capacitance control circuit and a variable capacitance control method by the variable capacitance control circuit including an MIM capacitor, multiple FET switches, and a control unit. The variable capacitance control method of the present invention obtains a desired variable capacitance value by outputting a control signal which turns on an FET among the multiple (n number) FET switches and turns off remaining (n-1) FET switches by the control unit to multiple FET switches. The present invention increases a Q value (Q=1/RC) by reducing an overall FET on-resistance value by using a control way which turns on an FET switch among the N number of FET switches and turns off remaining FET switches and thereby optimizes power consumption in a power amplifier (PA) and a reception rate in a low noise amplifier (LNA).
