The book is very nicely written and has lots of practical tips, rule of thumbs which a practicing high speed CMOS circuit design engineer needs. Its conscise and works as good referance.

The IBM authors wrote a concise reference manual on circuit
design, process variation effects on circuits, and time borrowing. What is missing? Sections on sequential circuit design, transistor sizing techniques, or modeling circuits through mathematics, spice and verilog. However, this is among the most lucid texts written on circuit structures to date.

It's concise but deals the topics in depth. It's much better and practical than usual vlsi text books.
