Abstract

Varactor and reference oscillator structures are provided that are particularly suited for integrated circuit fabrication and which provide excellent parameter performance (e.g., monotonicity, linearity, low phase noise and low differential and integral non-linearity) so that they are useful in a variety of wireless communication structures (e.g., cellular telephones).
