ET4371 Mixed-mode wireless transceivers
The past several years have successfully brought all-digital techniques to radio frequency (RF) frequency synthesizers and transmitters, as well as digitally-intensive techniques to receivers. In addition, digital assistance is applied to RF circuits to improve performance and power consumption.
This course will introduce the concepts of the digital RF approach and walk through the major building blocks that comprise new RF transceiver architectures. Emphasis is placed on
- Conventional charge-pump PLL and all-digital phase-locked loop (ADPLL) comprising: digitally-controlled oscillator (DCO), time-to-digital converter (TDC), and digital loop filter (HW1);
- All-digital transmitters featuring polar or Cartesian signal processing in digitally-controlled power amplifiers (DPA) with wideband modulation capabilities possibly including Quadrature clock generation (HW2);
- Direct-sampling discrete-time receivers comprising switched-cap circuits that perform various FIR and IIR filter operations (HW3).
Exercises and projects use Matlab/ADS to model and simulate the above three subsystems.
