Title:
VARIABLE ELECTRONIC ELEMENT AND CIRCUIT DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/080253
Kind Code:
A1
Abstract:
This variable-capacity element (100) comprises a switch unit (10) constituting a field effect transistor, and an element unit (20) that is electrically connected to the switch unit (10) and that constitutes a capacitor (passive element). This element unit (20) has a terminal electrode (5a) (first terminal electrode) electrically connected to a source electrode (5), and a terminal electrode (22) (second terminal electrode) that constitutes a first capacitor (first passive element) together with the source electrode (5) and that constitutes a second capacitor (second passive element) together with at least a drain electrode (6).
