Research

research overview

  • Dr. Barton’s RF Power Laboratory investigates engineering challenges related to RF and microwave active circuit design. Currently, the group is focused on making RF front-ends and related components more energy efficient. Her research in novel MMIC and hybrid power amplifier architectures addresses the performance tradeoffs (such as linearity vs. efficiency) in conventional designs. Examples include a novel RF-input load modulated balanced amplifier topology and related techniques employing load modulation, as well as RF front-ends that can be reconfigured in operating frequency, signal characteristics, or load impedance. Other thrusts of Dr. Barton's research group include analog sensor technologies integrated with power amplifiers in GaN and related high-performance technologies. Examples include integrated temperature and impedance sensors for in-situ monitoring of environmental factor that affect reliability and performance.

Teaching

courses taught

  • ECEN 3250 - Microelectronics
    Primary Instructor - Spring 2018
    Develops a basic understanding of active semiconductor devices. Focuses on building an understanding of BJT and CMOS devices in both digital and analog applications.
  • ECEN 3400 - Electromagnetic Fields and Waves
    Primary Instructor - Fall 2019
    Electromagnetic fields are covered at an introductory level, starting with electrostatics and continuing with DC current, magnetostatics, time-varying magnetic fields, waves on transmission lines, Maxwell's equations and the basics of plane waves. The use of fields in inductors, capacitors, resistors, transformers, and energy and power concepts are studied.
  • ECEN 4634 - Microwave and RF Laboratory
    Primary Instructor - Fall 2018
    Introduce RF and microwave measurement methods. A laboratory course whose experiments build on material learned in ECEN 3410: electromagnetic waves, transmission lines, waveguides, time-domain reflection, frequency-domain measurement, microwave networks, impedance matching, antenna pattern measurement, radar and simple nonlinear concepts such as harmonics, square-law detection, mixing and transmitter/receiver applications. Same as ECEN 5634.
  • ECEN 5024 - Special Topics
    Primary Instructor - Spring 2019
    Same as ECEN 4024.
