Recent developments in the IGNITE project on front-end design in CMOS 28-nm technology

The IGNITE project (INFN Ground -up INITiative-on micro -Electronics developments) is developing solutions on integrated micro -systems aimed at the next generation of high -luminosity experiment at the LHC. A test ASIC, designed in CMOS 28-nm technology and named Ignite -0, has been submitted for fabrication. It integrates circuital solutions suitable for pixels with timing having a pitch ranging from 45 to 55 mu m. The present paper describes the criteria used in the design choices, and the expected ASIC performance as output from post -layout simulations. Perspectives on subsequent design work on 4D -tracking devices following the Ignite -0 development are also briefly described.
