This letter presents an inductorless 64-GBaud linear differential transimpedance amplifier (TIA) design for a coherent optical receiver in 0.13 µm SiGe BiCMOS with superior dynamic range performance. The two stage topology of the design with a common-base (CB) input stage and a shunt-feedback (SFB) amplification stage extends the TIA bandwidth with high frequency peaking without degrading noise performance. The two cascaded VGAs in the amplifier stage extend the input dynamic range with total harmonic distortion (THD) <2% for 600 mVpp output at 3.2 mApp input photodiode current. Measured transimpedance gain ZT is 72 dBΩ with -3 dB bandwidth greater than 67 GHz and gain dynamic range of 30 dB.
