Abstract
This paper presents the design and simulations of a 224-Gb/s inverter-based transimpedance amplifier (TIA) designed in 28-nm CMOS process. The co-design of the photodiode and CMOS TIA efficiently optimize the optical receiver. The TIA achieves the bandwidth enhancement with the distributed peaking and interleaved active-feedback (IAFB) technology. The simulations result show that the proposed TIA has 39-dBΩ transimpedance gain and 70-GHz bandwidth (BW). Overall, it achieves a clear 224-Gb/s PAM4 eye diagram. The total power consumption is 20.7mW at 0.9-V supply voltage. And the input referred noise current is 8.2uArms.
