A 40 Gbit/s transimpedance amplifier (TIA) implemented in 0.13 µm SiGe BiCMOS with high linearity range is presented. The TIA features 24.2 dB (65.2 dB Ω) gain, a bandwidth of 34.2 GHz and a power consumption of only 80 mW from a 2.5 V supply. Total harmonic distortion is less than 5% up to an input current of 1.3 mApp.
