A 63.74 Dbo Gain 60.84 Ghz Bandwidth Power-efficient Transimpedance Amplifier in 130 Nm Sige Bicmos Technology

Lavakumar Navilipuri and Andy Heinig,Fraunhofer Institute for Integrated Circuits IIS/EAS, Germany


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 dBO and a bandwidth of 60.84 GHz after layout implementation, making it suitable for high-speed data transmission applications. The TIA also demonstrates low input-referred noise of 16.20 pA/vHz and consumes only 31.53 mW 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 contributes to the advancement of high-speed optical communication systems by providing a simple yet effective TIA design that balances performance, efficiency, and simplicity.

Exploring Transimpedance Amplifier Topologies: Design Considerations and Trade-offs

Lavakumar Navilipuri and Andy Heinig, Fraunhofer Institute for Integrated Circuits IIS/EAS, Germany


Transimpedance amplifiers (TIAs) play a crucial role in converting current signals from sensors, photodiodes, and other transducers into voltage signals for processing in various electronic systems. In this paper, we explore three distinct TIA topologies: common emitter with negative resistive feedback, regulated cascode, and Darlington pair with negative resistive feedback. Each topology offers unique advantages and trade-offs in terms of bandwidth, gain, and noise performance. We analyze the characteristics of each topology, discussing their impact on TIA design and performance. Through theoretical analysis and circuit simulations, we investigate methods to optimize gain, bandwidth, and noise performance for different application requirements. Our findings provide valuable insights into TIA design considerations, offering engineers a comprehensive understanding of TIA topologies and their implications for electronic system design.

Evaluation of as-built Electrical Services for Future Solar Hybrid Integration in 500-capacity Student Hostels

Habeeb Olayiwola, Olorukooba and Peter Olabisi, Oluseyi, Department of Electrical and Electronics Engineering, University of Lagos, Lagos, Nigeria


This study examines the as-built electrical system of a 500-capacity student hostel at the University of Lagos to evaluate its readiness for integrating a solar hybrid power system. Through analyzing construction plans and comparing them to the actual installation, the research highlights deviations and their potential impact on future renewable energy additions. The study proposes a 500kVA transformer for the building and determines that, while deviations exist, the installed cabling seems adequate for this capacity. Moreover, using PVsyst software, the available space is deemed suitable for a solar farm potentially powering 25% of the total load.This research stresses the need for strict construction adherence to energy-efficient designs. It further shows the viability of incorporating solar power into existing infrastructure to reduce energy costs and support sustainable campus development.
