A 2.5Gb/s CMOS transimpedance amplifier using novel active inductor load

A high-speed and low power transimpedance amplifier for 2.5Gb/s applications has been implemented in 0.35µm CMOS technology. For higher transimpedance gain and wider bandwidth, in this paper, an inductive shunt peaking technique is applied using a novel active inductor load that can be used at 1 ∼ 2GHz range. Measured performance shows 1.45GHz bandwidth with 57dBΩ transimpedance gain and the power consumption of about 50mW.
