可变电容器和电子装置
摘要：
可变电容器和电子装置。一种可变电容器包括：电容器，所述电容器串联连接在第一信号端子与第二信号端子之间，所述电容器的电容根据施加于可变端子的可变电压而改变；第一电阻器，所述第一电阻器连接在电容器中的相邻电容器之间的第一节点与可变端子之间；第二电阻器，该第二电阻器连接在电容器中的相邻电容器之间的第二节点与固定端子之间，该固定端子被施加有固定电压；以及第三电阻器，该第三电阻器连接在第三节点与固定端子之间，第三节点位于第一和/或第二信号端子与电容器中离第一和/或第二信号端子最近的电容器之间，其中，第二电阻器的电阻与第三电阻器的电阻之比小于1且大于1/2，并且第二电阻器的电阻不等于第一电阻器的电阻。
摘要（英）：

A variable capacitor includes: capacitors connected in series between first and second signal terminals, capacitances of the capacitors varying in accordance with variable voltage applied to a variable terminal; a first resistor connected between a first node between adjacent capacitors of the capacitors and the variable terminal, a second resistor connected between a second node between adjacentcapacitors of the capacitors and a fixed terminal applied with fixed voltage, and a third resistor connected between a third node and the fixed terminal, the third node being located between the firstand/or second signal terminal and a capacitor located closest to the first and/or signal terminal among the capacitors, wherein a resistance of the second resistor is less than 1 and 1 2 or greaterwith respect to a resistance of the third resistor, and the resistance of the second resistor is not equal to a resistance of the first resistor.
