摘要：
An adjustable capacitor is provided including a capacitor unit including a plurality of capacitor groups aligned in a matrix format and a switch unit to adjust capacitance by connecting the plurality of capacitor groups in parallel according to a selection signal of a column and row of the matrix. Accordingly, the adjustable capacitor may be realized of a small size but with a high capacitance change rate.
