TIA optimization for optical network receivers for multi-core systems-in-package

Transimpedance amplifiers (TIAs) are crucial elements in optical links. A simulation supported optimization study for different single ended TIAs was performed. Based on ST65nm CMOS technology, utilization scenario dependent solutions are presented, as well as an optimized solution for on-package multi-core optical network receivers. A key result of our study is the superiority of the push-pull topology over the common source topology and we argue for optimizing TIAs for designated DC input currents.
