I agree that the material is well presented and comprehensive but be aware that much of the derivation is first for bipolar circuits and only secondarily for CMOS, often with reference back to the development of the bipolar counterparts. So unless your interested in delving into bipolar circuits as well as CMOS you may prefer a text devoted to CMOS-only analog IC design.
