- Choose an an appropriate design methodology for creating amplifiers based on a set of specifications and for a specific application.
- Quantify the effects of noise, process and temperature variations on the performances of analog circuits used for biasing, amplification and filtering
- Analyze the trade-offs between "linearity, noise, power consumption and speed" in analog design.
- Assess / Evaluate the strengths and weaknesses of different analog and mixed-signal circuit architectures with respect to these trade-offs
- Manipulate state-of-the-art industrial EDA tools (Cadence "Virtuoso, Assura, Spectre", and design kits (e.g. UMC 65 nm CMOS technology).
