Background & Research Interests

Mr. Camenisch received his BS degree from the Milwaukee School of Engineering in 1980 and has since been employed by the Medical College of Wisconsin.

Major interest and expertise is in the design of:

  • Pre-A/D signal conditioning circuitry
  • Low noise amplifiers
  • Fast settling amplifiers
  • Filters

Experience specific to EPR:

  • EPR bridge design, including both microwave and electronic aspects of construction
  • Saturation recovery bridge and signal conditioning system design
  • Involvement in the design or modification of L-, S-, C-, K-, and Q-band bridges
