Abstract
In this paper, a low noise and high bandwidth transimpedance amplifier (TIA) is designed for optical receiver using a 0.18 μm standard in CMOS technology. The proposed circuit operates at a data rate of 13.25 Gb/s. Employing a series inductive peaking technique, an improvement of bandwidth by only one inductor within the structure is achieved to reach a wide bandwidth of 9.28 GHz. The gain of this amplifier is 53 dB at 9.28 GHz and its input current noise is about 36.12 pA/√Hz.
