Title:
VARIABLE CAPACITOR MODULE
Document Type and Number:
WIPO Patent Application WO/2017/187952
Kind Code:
A1
Abstract:
A variable capacitor module (10) has an output circuit (12), a reception circuit (13), a first resistor (R1), a capacitor (C1) wherein capacitance changes corresponding to a voltage applied, a first output terminal (t11), and a second output terminal (t12). The output circuit (12) has one or a plurality of light emitting diodes (12a), and outputs light corresponding to a setting signal. The reception circuit (13) has one or a plurality of photodiodes (PD1-PDn) connected in series, receives the light outputted from the output circuit (12), and generates a current. The resistor (R1) is electrically connected to the reception circuit (13), and converts, into a voltage (V1), the current thus generated by the reception circuit (13). A capacitance corresponding to the voltage (V1) thus converted by the resistor (R1) is set in the capacitor (C1).
