This volume brings together papers from the 23rd European Solid-State Circuits Conference (ESSCIRC), held in 1997. It presents research and development work in solid-state circuit design, semiconductor devices, and integrated systems, reflecting the state of the field at the close of the twentieth century. The proceedings are aimed at electrical engineers, circuit designers, researchers, and technical libraries interested in analog, digital, mixed-signal, radio-frequency, and memory-related circuit technologies. As a conference record, the book preserves session contributions, technical discussions, and professional exchange from a major European microelectronics event. The volume is useful as a historical reference for the evolution of integrated-circuit design practices and as a source for researchers tracing developments in semiconductor and circuit engineering.
