This paper presents a 10-Gbps optical receiver with monolithically integrated CMOS photo detector. A transimpedance amplifier with nested feedback and shunt-peaking is proposed for broad-band and high gain operations. Incorporating a 2-D meshed spatially-modulated light detector, the optical receiver is capable of delivering 25 kΩ transimpedance gain when driving 50 Ω output loads. The operating speed is improved by 3X over the prior art with the same technology. Implemented in a generic 0.18-µm CMOS technology, the chip size is 0.95 mm × 0.8 mm. This receiver core drains 118 mW from 1.8 V supply.
