ET4371 Advanced 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 the:

• 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 (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.

Study Goals In-depth knowledge of all-digital PLL, digital transmitters and the discrete-time receiver
