Parasitic-Aware Optimization of CMOS RF Circuits by David J. Allstot

In the arena of Parasitic-Aware Design of CMOS RF Circuits, efforts are aimed at the realization of true single-chip radios with few, if any, off-chip components. Ironically, the on-chip passive components required for RF integration pose miore serious challenges to SOC integration than the active CMOS and BJT devices. This is not surprising since modern digital IC designs are dominated as much, or more, by interconnectg characteristics than by active device properties. In any event, the co-integration of active and passive devices in RFIC design represents a serious design problem and an even more daunting manufacturing challenge. If conventional mixed-signal design techniques are employed, parasitics associated with passive elements (resistors, capacitors, inductors, transformers, pads, etc.) and the package effectively de-tune RF circuits rendering them sub-optimal or virtually useless. Hence, dealing with parasitics in an effective way as part of the design process is an essential emerging methodology in modern SOC design. The parasitic-aware RF circuit synthesis techinques described in this book effectively address this critical problem.
