A transimpedance amplifier (TIA)-optical receiver (Rx) using two intersecting active feedback system with regulated-cascode (RGC) input stage has been designed and implemented for optical interconnects. The optical TIA-Rx chip is designed in a 0.13 <i>μ</i>m CMOS technology and works up to 10 Gbps data rate. The TIA-Rx chip core occupies an area of 0.051 mm<sup>2</sup> with power consumption of 16.9 mW at 1.3 V. The measured input-referred noise of optical TIA-Rx is 20 pA/√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 408 GHzΩ/mW.
