Abstract :
In this work, new structures based on the PN junction are presented for the design of integrated varactors. In order to optimize the ratio capacitance per unit area (C/A), two varactor geometries have been developed: interdigitated and cross structures. Varactors have been characterized with a specific measurement methodology. A library of varactors that can be used in different RF applications has been implemented with good quality factors and a tuning range around 30%.
