A 64-Gbaud Transimpedance Amplifier in 130nm SiGe Technology with Effective Broadband Techniques

In this paper, a 64-Gbaud transimpedance amplifier in 130nm SiGe technology is presented. The π-network broadband technique and shunt-shunt RC feedback are proposed to achieve high gain and wide bandwidth simultaneously. The small-signal results show a transimpedance gain of 50.2 dBQ with a 3-dB ban...

Description
Summary:In this paper, a 64-Gbaud transimpedance amplifier in 130nm SiGe technology is presented. The π-network broadband technique and shunt-shunt RC feedback are proposed to achieve high gain and wide bandwidth simultaneously. The small-signal results show a transimpedance gain of 50.2 dBQ with a 3-dB bandwidth exceeding the measurement limit of 67 GHz. An eye-diagram of 64-Gbaud can be obtained with the time domain measurements. The proposed TIA consumes 34.5 mW and occupies a core area of only 0.1 mm 2 .
