Popis:	In this paper a transimpedance amplifier is presented, which features a bandwidth of 97 GHz, 66 dBΩ maximum transimpedance gain, and 6.3 pA/√Hz integrated noise current density, operating at up to 120 Gb/s and consuming only 145mW. Reaching a higher bandwidth at a noise performance comparable to the state-of-the-art, is the novelty of this work. It was achieved by combining a low-bandwidth input stage, reducing the total noise, and a multi-stage post equalization. The gain peaking technique through cascading emitter follower stages is employed in a broadband transimpedance amplifier as a post equalizer. To the best of the author’s knowledge, the presented design shows the best performance in terms of overall gain, bandwidth, and noise for the lowest power consumption compared to state-of-the-art designs.
