Problems solved by technology

[0006] Therefore, with a conventional capacitor circuit that uses capacitance to tune frequency by using a binary weighting method, it is difficult to tune uniformly when the frequency band changes, so there is a problem that it cannot be tuned to the extent desired by the user

Abstract

A capacitor circuit of a multi-group array type according to one embodiment of the present invention comprises: a first capacitor group including first to m-th switch-capacitor circuits connected in parallel with each other, the first to m-th switch-capacitor circuits have capacitances different from each other according to a first weight; and a second capacitor bank connected in parallel with the first capacitor bank and including first to m-th switch-capacitor circuits connected in parallel with each other, in which the first to m-th switch-capacitor circuits have different capacitances according to a second weight, the second weight is different from the first weight.

Description

technical field [0001] The present invention relates to a capacitor circuit of a multi-group array type and a variable capacitance circuit having the capacitor circuit. Background technique [0002] Often, different frequency bands are used in the RF domain, and in the process of integrating these different frequency bands, it becomes increasingly difficult and complex to design an antenna that can use all of the multiple frequency bands. Therefore, there is a need for a switch capable of switching the impedance of the antenna. [0003] Typically, when a capacitor array is used to set various capacitance values, the design is conventionally performed using a binary weighting method. [0004] However, the binary weighting method is not suitable for tuning the capacitance used for antenna impedance tuning. [0005] A conventional multi-group array type capacitor circuit includes a binary weighted array capacitor using a binary weighted array, although it is simple, the distr...
