Digital systems implemented with high-speed transistor technologies face a variety of design challenges in an effort to keep pace with the accelerating demand for performance. As device switching frequencies climb comfortably into the gigahertz range, clock skew in digital systems threatens to limit the advantages of synchronous pipelined designs. This research investigates the limitations of clock skew on high-speed digital systems by designing and simulating an 8x8 bit synchronous, pipelined multiplier using Indium phosphide (InP), heterostructure bipolar junction (HBT) transistor technology. Fundamentals of circuit analysis and the principles of junction transistor behavior are applied to design an optimal family of logic devices using current-mode logic. All testing and simulation data is based upon results obtained from Tanner SPICE design tools. Using the building blocks of this logic family, an array multiplier is constructed and further configured into five distinct pipeline implementations. By employing a different number of pipeline stages in each implementation, the trade-offs of pipelining are illustrated and clock skew is analyzed at a variety of throughput rates. Finally, the impact of clock skew on throughput performance is quantified and summarized as a reference point for further research into asynchronous control techniques.Naval Postgraduate School Monterey CA is the author of 'Design of a Synchronous Pipelined Multiplier and Analysis of Clock Skew in High-Speed Digital Systems' with ISBN 9781423531470 and ISBN 1423531477.
