The School of Electrical & Electronic Engineering (EEE) invites applications for the position of Research Associate (Transistor Modeling).

Key Responsibilities:

• Work on a project to develop a compact model for transistor high-frequency operations that is scalable over geometry, dc bias, and doping concentrations
• Work on extending a GaN-HEMT compact model (using Verilog-A) for RF modeling using physics-based sub-circuit
• Generate numerical dc IV and S-parameter data for the GaN-HEMT for model validation
• Extract model parameters using numerical data and devise a general procedure for parameter extraction
• Run compact model in circuit simulation and compare with numerical data
• Study and verify model scalability in gate/access-region lengths, dc biases, substrate doping concentrations
• Extend the model and modeling approach to generic Si-MOSFETs
• Formulate and implement the sub-surface compact model for a GaN-HEMT using Verilog-A in sub-circuit RF modeling
• Run dc/ac and frequency analyses of the developed sub-circuit RF model using SPICE in Cadence tools
• Construct the corresponding GaN-HEMT device in Silvaco tools and obtain numerical data (dc-IV and S-parameters) of various geometries, biases, and doping concentrations
• Devise parameter extraction strategies for the developed compact model
• Compare and validate the compact model with numerical data for scalable RF model
