Responsibilities
Designing, simulating, and analyzing high-speed electrical & optical systems and components
Develop models for high-speed optical drivers used to drive Silicon Photonic (SiPho) modulators
Model the electrical characteristics of optical drivers to ensure the proper transmission of high-speed signals to optical modulators
Focus on key parameters like pulse shaping, voltage swing, and rise/fall time to achieve the required data rates
Simulate the performance of the optical driver under various operating conditions, including temperature variations and voltage fluctuations
Develop models for TIA circuits, which convert the photocurrent generated by photodetectors into a voltage signal
Model key aspects of TIAs, including feedback resistors, bandwidth, noise characteristics, and linearity to ensure high sensitivity and low distortion
Analyze the impact of thermal noise, shot noise, and jitter on TIA performance in high-speed applications
Develop accurate and efficient models for high-speed SerDes interfaces, focusing on both the transmitter and receiver
Model the electrical behavior of high-speed I/O circuits, considering factors like clock data recovery (CDR), equalization, and voltage swing
Use simulation tools to simulate the performance of SerDes systems in both ideal and non-ideal conditions
Perform signal integrity simulations, including eye diagram analysis, bit error rate (BER) analysis, and jitter analysis for SerDes I/O interfaces
Model and analyze the impact of noise, crosstalk, skew, and reflections on the signal quality and timing in high-speed links
Implement and simulate techniques like channel equalization, pre-emphasis, and de-emphasis to mitigate signal degradation
