The course provides advanced knowledge on the design of RF circuits using MMIC or RFIC techniques.
1.Transceivers’ architectures and RF basics
Black box schematic of a RF transceiver; non linearity issues: desensitization, cross-modulation, CP and IIP3, cascaded of non-linearity; noise issue: NF. Receiver sensitivity, selectivity and dynamic range. Super-heterodyne receiver: architecture, advantages and issues. Homodyne receiver: architecture, advantages and issues. Image-rejection receivers: Hartley and Weaver solutions. Transmitter’s ACP. Transmitter architectures: direct-conversion and double conversion: advantages and issues..
Noise, power and line matching. Matching networks: using discrete components or microstrip. Stub: single and double stub matching techniques. Using the Smith chart in the design of the matching networks.
3.LNA (Low Noise Amplifier)
Gain consideration: power gain, transducer power gain and available power gain; Noise consideration. Stability consideration. Constant gain, noise and stability circles. Amplifier design: optimizing for power and noise. Design of integrated LNA.
Mixer spec.s. Design of single transistor mixers. Integrated mixers.
5.VCO and PLL
Design of RF VCO. Phase noise and tuning range.
Harmonic-balance and SpectreRF.
Design and simulation of RF blocks (mixer, lna, VCO) using ADS.
The exam consists of:
- report on the design activity with ADS
- oral part
