fJscaler samples 100 GHz BiCMOS TIA for AI, cloud datacenter optical links

fJscaler has begun sampling to strategic customers its BiCMOS transimpedance amplifier (TIA) for intensity-modulation direct-detection (IM-DD) applications, designed for next-generation optical interconnects powering AI and cloud datacenters. The device delivers an energy efficiency of 0.85 pJ/bit, an input-referred noise density of 18 pA/√Hz, and a bandwidth of 100 GHz.
