Abstract
An impedance matching circuit is connected to a first circuit block (impedance matching target circuit) that requires impedance matching and that has one terminal connected to a signal line and the other terminal connected to a ground, the impedance matching circuit having a second circuit block that has a first circuit and a second circuit connected in parallel. In the first circuit, a first capacitor having a variable capacitance and a first inductor having a first inductance are connected in series, and in the second circuit, a second inductor having a second inductance and a switch are connected are connected in series. The impedance matching circuit has one terminal connected to the signal line of the first circuit block and the other terminal connected to the ground of the first circuit block.
