Abstract
Described herein is an apparatus that includes a varactor and an inductor to form a resonant circuit that oscillates at a resonant frequency. The resonant frequency is a function of a pressure of a gas within an aperture of the varactor. In some embodiment, the varactor includes a first layer of p-type material, a first layer of n-type material, and a first np junction formed between the layer of p-type material and the layer of n-type material. The aperture extends at least partially through the layer of p-type material, at least partially through the layer of n-type material, and entirely through the np junction.
