Title:
CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2007/116566
Kind Code:
A1
Abstract:
In a capacitor, the capacitance of which is changed by an externally applied DC
bias, the number of stacked electrodes equipped in the capacitor main body is
reduced and a voltage required for applying the DC bias is also reduced. The capacitor
main body (23) is provided with a DC bias applying electrode (25), a capacitance
acquiring electrode (26), and an earth electrode (24). The DC bias applying electrode
(25) is positioned between the capacitance acquiring electrode (26) and the
earth electrode (24). The earth electrode (24) is made to serve not only as an electrode
for applying the DC bias but also as an electrode for acquiring the capacitance.
