Wireless and Wireline Integrated Circuits and Systems

This research area is connected to the Circuit Laboratory for Advanced Sensors and Systems (CLASS) at ESL. 

ESL has made significant contributions to radio frequency and mm-wave circuits and systems. Research activities in this area focus on high-performance wireless and wireline transceivers at both circuits and systems levels. Researchers are also exploring new architectures in low-cost CMOS technology and high-speed and/or high-power III-V technologies such as GaAs/InP/GaN. ESL possesses the capability to conduct mixed-signal, RF and mm-wave measurement and characterization, both on-die and in-package, supporting a wide range of frequencies from DC-110 GHz.

Current research projects include: 

  • Direct Digital-to-RF Transmitters and Power Amplifiers 
  • Digital Beamforming Architecture and Circuits 
  • High Resolution GHz-speed Digital-to-Analog Converters (DACs) 
  • Digital Time and Amplitude Calibration Techniques for DACs 
  • Ultra-Wide Tuning Range and Low Phase Noise mm-Wave LC Voltage-Controlled Oscillators (VCOs) 
  • Integrated Circuits Reliability 
  • Adaptive Power Management Circuits 
 The success of the research is a result of:
  • Interdisciplinary program involving DSP & communications for building complete “Antenna-to-Bit” Radio solutions
  • State-of-the-art infrastructure including CAD tools, wafer/package test facilities, and access to in house and external foundries
  • Timely, relevant education and student training programs
