Integrated Video-Frequency Continuous-Time Filters, 1995
High-Performance Realizations in BiCMOS
The Springer International Series in Engineering and Computer Science Series, Vol. 323

Advances in the state of the art mean the signal processing ICs of ever-increasing complexity are being introduced. While the typical portion of a large IC devoted to analog circuits has diminished, the performance of those surviving analog signal processing circuits remains vital and their design challenging. Moreover, the emerging high-definition TV technology has created a new area for IC development, one with formidable signal processing requirements. The antialiasing filters needed for one proposed HDTV decoder motivated the research documented in this book. Sharply selective filters place tight constraints on the permitted excess phase shifts of their constituent circuits. Combined with stringent requirements for low distortion at video frequencies, these constraints challenge the IC filter designer.
Integrated Video-Frequency Continuous-Time Filters: High-PerformanceRealizations in BiCMOS deals with what is arguably the mainstay of analog signal processing circuits. Prominent applications in computer disk-drive read channels, video receivers, rf circuits, and antialiasing and reconstruction in data converters testifies to their importance. Moreover, they are excellent benchmarks for more general analog signal processors. Bipolar and MOSFET transistors, freely combined at the lowest circuit levels, provide the designer with an opportunity to develop potent variations on the standard idioms. The book considers the general principles of BiCMOS circuit design, through to a demanding design problem. This case-study approach allows a concrete discussion of the justification for and practical trade-offs of each design decision.
Audience: A reference work for experienced IC designers and a text for advanced IC design students.
