Abstract
A resistor (-) and a resistor (-) are connected in parallel with each other between a source of an input transistor (-) and the ground. A switch (-) is provided between the resistor (-) and the source. A variable resistor circuit may be constituted by the resistor (-), the resistor (-) and the switch (-). Further, a capacitor (-) and a variable capacitor (-) are connected in series with each other between the source and the ground. A control terminal (-) to which a voltage is applied when capacitance of the variable capacitor (-) is controlled is provided between the capacitor (-) and the variable capacitor (-). A variable capacitor circuit may be constituted by the capacitor (-) and the variable capacitor (-). An input capacitance change circuit may be constituted by the variable resistor circuit and the variable capacitor circuit.
