A 63.74 DBΩ gain 60.84 GHZ bandwidth power-efficient transimpedance amplifier in 130 NM SIGE BICMOS technology

This paper presents the design and analysis of a high-performance Transimpedance Amplifier (TIA) tailored for high-speed optical communication systems. The TIA utilizes a Darlington pair topology with Negative Resistive Feedback to achieve high transimpedance gain and wide bandwidth. Through detailed circuit analysis and simulation, the TIA exhibits a transimpedance gain of 63.7 dBΩ and a bandwidth of 60.84 GHz after layout implementation, making it suitable for high-speed data transmission applications. TheTIA also demonstrates lowinput-referred noise of 16.20 pA/√Hz and consumes only 31.53mW of DC power, highlighting its power efficiency. Comparative analysis with existing TIAs showcases the effectiveness of the proposed design, which achieves impressive performance without the need for additional circuitry. This study advances high-speed optical communication systems by presenting a TIA design that effectively balances performance, efficiency, and simplicity.
