Teaching Activities   Randy Geiger's teaching is dominantly focused to the greater electronics and circuits area at both the undergraduate and graduate level.  He regularly teaches undergraduate courses in electronics and analog and digital VLSI design.  Undergraduate courses he has taught in recent semesters include EE 201, EE 203, EE 230, EE 330, EE 434 and EE 435.  At the graduate level his teaching is primarily in the analog and mixed-signal VLSI design area.  Recent graduate courses he has taught include EE 501, EE 505 and EE 508.

Research Activities    Research interests are dominantly in the analog and mixed-signal VLSI field and on applications of this technology in other disciplines.  Recent research projects have focused on design and testing of both analog to digital (ADC) and digital to analog (DAC) converters, op amp design, integrated filter design, temperature sensors, voltage references, and design and layout strategies for performance optimization and yield enhancement.

Background                Randy Geiger received the BS degree in electrical engineering and the MS degree in mathematics from the University of Nebraska and the PhD degree in electrical engineering from Colorado State University.  From 1977 to 1990 he was a faculty member in the Electrical Engineering Department at Texas A&M University and since 1991 he has been a member of the faculty in the Department of Electrical and Computer Engineering at Iowa State University where he currently holds the title Willard and Leitha Richardson Professor.  He is a past president of the IEEE Circuits and Systems Society (CAS), a past chair of the Transactions Committee of the IEEE Periodicals Council, and a past member of the IEEE Publications Board.   He was the recipient of the IEEE Millennium Medal and the IEEE CAS Society Golden Jubilee Award, and is a Fellow of the IEEE.
