Claim 19:
20. A temperature-dependent capacitor comprising:
a first conductive plate;
a second conductive plate located in a parallel-planar orientation to the first conductive plate,
wherein the first conductive plate is adapted such that a distance between at least a portion of the first conductive plate and at least a portion of the second conductive plate decreases as a temperature of the first conductive plate increases; and
a dielectric separating the first conductive plate from the second conductive plate, the dielectric including a combination of two or more distinct dielectric materials arranged in layers between the first and second conductive plates, the two or more distinct dielectric materials including:
a first dielectric material arranged adjacent to the second conductive plate, wherein there is a positive correlation between temperature of the first dielectric material and dielectric constant (ε) value of the first dielectric material; and
a second dielectric material arranged adjacent to the first conductive plate, the first dielectric material being sufficiently flexible to allow movement of the first conductive plate relative to the second conductive plate in response to the increase in the temperature of the first conductive plate.
