Pedagogy for Course Delivery:
The class will be taught using theory based method. Since this is design course, students are given problems based on design of RF
circuits. Technology Discussion sessions are organized on current research challenges in RF circuit design, their relevance and
applications in industry. Design studies for various existing circuits are taken through seminar sessions which make students relate
their subject with practical implementation of theory.
Student Learning Outcomes:
 Able to understand analog CMOS designs.
 Able to understand the analysis and design of RF front-end systems including the circuits, blocks, and architectures.
 Able to design in the 50 ohm environment
 Able to Understand Transmission Lines to, from, and inside RFICs
 Able to Design with RFIC Package Parasitic
 Able to analyze RF device models: Transistor, Diode, R, L, C Transformer
