About Us

The Circuit Laboratory for Advanced Sensors and Systems (CLASS) was founded by Dr. Waleed Khalil in 2009 and is housed in the Electroscience Laboratory (ESL) complex. As part of the Ohio State University Department of Electrical and Computer Engineering, the ESL is a major center-of-excellence that has consistently maintained national and international preeminence in EM and Radio Frequency (RF) circuits & systems.

CLASS is sponsored by contracted research and collaboration with commercial and government organizations. The research is also enabled by shared experimental facilities of the ESL. The lab is equipped with state of the art infrastructure including CAD tools, wafer/package test facilities, and access to in house and external foundries.

Since its establishment, the lab has made significant contributions to RF and mm-wave circuits and systems. Research activities of the lab focus on high-speed wireline and wireless systems and mixed-signal circuits. Current research projects include:

  • Direct Digital-to-RF Transmitters Employing Mixer-less, ΔΣ and Pulse-Width Modulated Architectures
  • 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)
  • Negative Capacitance Circuits
  • Digital Beamforming Architecture and Circuits
  • Integrated Circuits Reliability
  • Power Management for Near-Threshold Chip Multi-Processors (CMPs)
