Title Statement Characterization, comparison and analysis of monolithic inductors in silicon for RF IC's / by Marc D.Rosales Physical Description vii, 149 leaves : ill General Note Thesis (M.S. Electrical Engineering)--University of the Philippines, Diliman Summary, Etc. Passive components implemented in digital CMOS is one of the major elements in any Radio Frequency CMOS research. The chip area this passive component occupies is very large compared to the area covered by the active component. Thus, this is enough reason to make a passive component a significant area of research. In addition, the performance of a passive element like an inductor greatly influences the overall system performance. This thesis focuses on the design, implementation, characterization and analysis of spiral inductors on a heavily doped silicon substrate using a 0.25 um CMOS process. The inductors were designed using Spiral Calc, Asitic and Virtuoso Layout Editor. A total of 23 structures were fabricated on an 8.942 mm(squared) die. The inductor test chip consisted a total of 19 spiral inductor structures and four structures for measurement calibration and test structure de-embedding. The inductor structures that were implemented included planar square spiral structures, planar octagonal spiral structures and multi-level square spiral structures. Some of these inductors had Q enhancement structures consisting of patterned ground shield, metal halos, multiple metal layers and a combination of multiple metal layers and patterned group shield. All inductors were placed inside a test fixture with group-signal-ground (GSG) probe pads. The additional structures implemented for measurement calibration and test fixture de-embedding included text fixtures with open GSG pads, shorted GSG pads, and thru GSG pads. The inductors including their Q enhancement structures were characterized using a network analyzer. A micromanipulator with microwave coplanar GSG probes, a Hewlett Packard network analyzer and post data processing using customized Matlab functions were used for de-embedding and extraction of the inductance, the structure parasitics and the Q-factor of the inductors. The generated data from the above set-up was used to produce two sets of plots for analysis and comparison. The first set was the set of measured data, where the effects of different de-embedding techniques were compared. The next set of plots involved the data generated from simulations using ASITIC, inductance formulas, inductor models and the measured data. The inductor design tools, models and formulas were compared and verified with actual measured data Subject Added Entry - Topical Term Electric inductors   Metal oxide semiconductors, Complementary   Silicon -- Electric properties Collection Category FI   UP Location UP DARCHIVES LG 995 2003 E64 R67 Regular Circulation UARD-10431T   UP DENG-II LG 995 2003 E64 R67 E2000000390 Room-Use Only E-487T   UP DARCHIVES LG 995 2003 E64 R67 Regular Circulation UARD-10431T   UP DENG-II LG 995 2003 E64 R67 E2000000390 Room-Use Only E-487T Textual Physical Form Designator Thesis           Physical Location University of the Philippines Diliman Main Library: University Archives LG 995 2003 E64 R67 Diliman: College of Engineering Library II LG 995 2003 E64 / R67           Digital Copy Not Available          Add to Book Cart  |   Download MARC
