Query: CMOS IC Layout book review

I have been a layout designer for 10 years and this is the first book I have found that is devoted exclusively to ic layout. It is about time. Your book does a good job of covering layout in the broad sense which make sit good for beginners and junior layout designers. I especially think you did a good job explaining the concepts of layers, basic design rules and transistor fingering. I do feel that you could have spent more time with transistor, resistor and capacitor matching from an analog perspective. Like most text and tools, your emphasis was on digital circuit. Keep up the good work and I look forward to the 2nd edition...
