Abstract :
Circuit analyses and performance optimization are presented of three basic BiCMOS digital circuit structures: BiCMOS buffer, NMOS/CML (coupled-mode logic), and ECL (emitter-coupled logic)/CMOS interface circuits. The analytical modeling of the transient behavior offers insight into the critical circuit and device parameters that affect the performance of these circuits. Techniques to improve the speed of each structure and the tradeoff factors involved in designing such circuits are discussed. The derived delay expressions can also be used in CAD tools for optimizing BiCMOS circuits and systems
