Beschreibung
Varactors are passive semiconductor devices used in electroniccircuits, as a voltage-controlled way of storing energy in order toboost the amount of electric charge produced. In the past, the useof low-cost fabrication processes such as complementary metal oxidesemiconductor (CMOS) and silicon germanium (SiGe) were kept forintegrated circuits working in frequency ranges below the GHz. Now,the increased working frequency of radio frequency integratedcircuits (RF ICs) for communication devices, and the trend ofsystem-on-chip technology, has pushed the requirements of varactorsto the limit. As the frequency of RF applications continues torise, it is essential that passive devices such as varactors are ofoptimum quality, making this a critical design issue.
Initially describing the physical phenomena that occur inpassive devices within standard IC fabrication processes, Designand Characterization of Integrated Varactors for RFApplications goes on to:
* present information on the design of wide band electricalvaractor models (up to 5 GHz) which enable the accurate predictionof device performance;
* propose a specific methodology for the measurement ofintegrated varactors, covering on-wafer measurement structures, thecalibration process, and detailed descriptions of the requiredequipment;
* explain de-embedding techniques and also analyse confidencelevel and uncertainty linked to the test set-up;
* examine the design of a voltage controlled oscillator (VCO)circuit as a practical example of the employment of methodsdiscussed in the book.
Providing the reader with the necessary technical knowledge fordealing with challenging VCO designs, this book is an essentialguide for practising RF and microwave engineers working on thedesign of electronic devices for integrated circuits. It is also auseful reference for postgraduate students and researchersinterested in electronic design for RF applications.
