Passive components, including spiral inductors and transformers, fabricated on silicon-based substrates are placing an increasing demand on radio-frequency integrated circuit (RFIC) design. Performance of the RFIC suffers from several non-ideal effects that must be taken into account in order to create a successful design. In particular, monolithic transformers can be...
Magnetically coupled passive transformers are increasingly integrated on-chip for
various analog and radio frequency (RF) applications including direct current
(DC) isolation, impedance transformation/matching, and conversion between
single-ended and differential signals. A primary motivation for the on-chip
integration of transformers is the overall size reduction and reduced cost.
However, the performance...
The electrical behavior of on-chip interconnects has become a dominant factor in silicon-based high speed, RF, and mixed-signal integrated circuits. In particular, the frequency-dependent loss mechanisms in heavily-doped silicon substrates can have a large influence on the transmission characteristics of on-chip interconnects. To optimize the performance of the integrated circuit,...
