VARIABLE CAPACITANCE CIRCUIT

摘要

The present invention relates to a variable capacitance circuit. According to the present invention, disclosed is a variable capacitance circuit which comprises multiple capacitance circuit parts including at least one switched capacitor unit connected in parallel respectively between a first terminal and a second terminal where a signal is inputted and outputted to provide capacitance; and a switch module having multiple switches stacked between the second terminal and a first ground terminal, wherein the switched capacitor unit comprises a switch part switching a forming path of the capacitance; and a capacitor part providing the capacitance through the path formed according to the switching of the switch part.
