Abstract
This paper presents a 6 Gb/s 4-channel arrayed transimpedance amplifiers (TIA) with the gain control for 4-channel passive optical network in 0.13 m complementary metal oxide semiconductor (CMOS) technology. A regulated cascode input stage and inductive-series peaking are proposed in order to increase the bandwidth. Also, a variable gain control is implemented to provide flexibility to the overall system. The TIA has a maximum 98.1 dBΩ gain and an input current noise level of about 37.8 pA/Hz. The die area of the fabricated TIA is 1.9 mm x 2.2 mm for 4-channel. The power dissipation is 47.64 mW/1ch.
