Abstract:
This paper presents several amplifier circuits for use with strain gauges. The circuits are inherently linear, produce four times the output of the standard Wheatstone bridge, and can easily be extended to accommodate multiple strain gauges. The implementation platform is the low-cost operational amplifier instead of the more expensive instrumentation amplifier, and circuit functionality has been verified using PSPICE simulations, and laboratory tests.

In 1997, he joined the Department of Electrical and Computer Engineering, University of Calgary, Calgary, AB, Canada, where he is currently a Professor. He completed a one-year Post-Doctoral Fellowship at Dalhousie University, where he was actively involved in its analog microelectronics group. After completing the fellowship, he taught at the University of the West Indies, was also a Visiting Professor at the University of Louisville, Louisville, KY, USA, for seven months. He was later with the defense industry for two years working on mixed signal projects. His current research interests include design of linear circuit elements, high-speed amplifier design, active analog filters, and CMOS circuits for signal processing and communication applications.
Dr. Maundy was an Associate Editor for the IEEE Transactions on Circuits and Systems I.
