A high quality factor varactor technology evaluation

Providing a high quality factor scalable varactor in an integrated technology is a wager. How to insure that your device will give the highest quality factor possible? In order to response this questions, we let the bases of a varactor gauge combining electrical performance and geometrical sizes. Giving a targeted capacitance, it could furnish a qualitive idea of the adequacy with technology performance. It could furnish also a indicator for comparison with other devices. As example of varactor gauge application, we present a comparison between two diode varactor devices in two BiCMOS technologies.
