Title:
可変容量素子及び共振回路
Document Type and Number:
Japanese Patent JP5085753
Kind Code:
B2
Abstract:
To provide a variable capacity element having a simpler configuration and excellent resistance to received voltage.
The variable capacity element includes a ferroelectric layer made of ferroelectric material, and two electrodes provided to sandwich the ferroelectric layer. The ferroelectric layer has characteristics such that it varies in capacity upon the application of a received signal of a predetermined frequency that is input from the outside, and that as the value of the received voltage increases within a predetermined voltage range within the range of variation of the received voltage value of the received signal, its volume decreases or increases.
