To meet these goals, design engineers are challenged to create high-performance, low-cost VCOs.

The Colpitts oscillator is a traditional design used for many VCO applications.

* ). Since the epitaxial layer for this kind of hyperabrupt varactor has relatively high resistivity, the series resistance is strongly dependent on the reverse voltage applied to varactor junction. The value of series resistance (RS)
