Wireline and Optical Circuits In response to the growing field of optical networks, there is a need for cost-effective and integrated solutions. Traditionally, high speeds and performance are prioritized at the expense of higher fabrication costs and lower ease of integration. As an alternative, fully bulk CMOS processes can be explored, utilizing Schottky photodiodes as photodetectors, deviating from established III-V technologies or hybrid approaches. Our research delves into the trade-off between performance and affordability by venturing into fully bulk CMOS processes. However, these processes impact photodiode efficiency, limiting the overall performance compared to current SotA implementations. This research aims to balance seamless integration into existing systems and technologies while minimizing compromises in performance.
The primary objective of this research is to develop an injection-locked clock receiver with Schottky photodiodes in bulk CMOS to achieve synchronization. This synchronization holds the potential to unify networks and enable cohesive system functionality over long distances. Despite challenges such as reduced responsivity in photodiodes, advancements in circuit design aim to ensure that this fully integrated solution maintains satisfactory performance levels. Ultimately, this research contributes to the evolution of optical communication systems by offering a more cost-effective and integration-friendly approach.
