Abstract

In this paper, a transimpedance amplifier (TIA)-optical receiver (Rx) using two intersecting active feedback system with regulated-cascode input stage has been designed and fabricated for optical interconnects. The optical TIA-Rx chip is designed with 130 nm CMOS technology and operates up to 10 Gb/s data rate. The TIA-Rx chip core occupies an area of 0.051mm2 with power consumption of 16.9 mW at 1.3 V. The measured input-referred noise of optical TIA-Rx is 20pA/√Hz with a 3-dB bandwidth of 6.9 GHz. The proposed TIA-Rx achieved a high gain-bandwidth product per DC power figure of merit of 408GHzΩ/mW .
