Two most interesting pieces of analysis I found are
- Nanavira Thera's Notes on Dhamma (http://www.nanavira.org/notes-on-dhamma/paticcasamuppada)
and
- Buddhadasa's "Practical Dependent Origination" (http://buddhasociety.com/online-books/buddhadasa-bhikkhu-paticcasamuppada-21-2#TOC and http://www.dhammatalks.net/Books6/Bhikkhu_Buddhadasa_Paticcasamuppada.htm)
a decent bibliography can be found at the end of Dhivan Thomas Jones' "New Light On The Twelve Nidanas" (http://www.academia.edu/2593517/New_Light_on_the_Twelve_Nidanas)
