【発明の名称】組み込みDCブロックを有する強誘電体
Document Type and Number:
Japanese Patent JP2002529938
Kind Code:
A
Abstract:
A voltage tunable dielectric varactor includes a tunable ferroelectric layer and first and second non-tunable dielectric layers. First and second electrodes positioned adjacent to the tunable ferroelectric layer form a tunable capacitor. A third electrode is positioned adjacent to the first non-tunable dielectric layer such that the third and first electrodes and the first non-tunable dielectric layer form a first blocking capacitor. A fourth electrode is positioned adjacent to the second non-tunable dielectric layer such that the fourth and second electrodes and the second non-tunable dielectric layer form a second blocking capacitor.
