Chip Design for Submicron Vlsi: CMOS Layout and Simulation

Good for learning about basic Chip Layout

As the author mentioned that the book is a basic introduction to submicron CMOS designs,you will find the book contents organized into short chapters with a level of details that one can study and understand within a short period.The software that comes with the book is a nice tool to start learning CMOS VLSI layout and simulation.It would be best to practice as you read and understand each section or topic.You can learn much from hands on by doing your own version of layouts or circuits for simulation.Each figure of a layout shown in the book is usually large enough to clearly see the details.Thus, you can try to recreate your own layout as seen from the figure.
Contents: 406 pages of content, Each chapter contains a short list of References and a few excercise problems at the end of each chapter.
