Portland State computer engineer Christof Teuscher inspired by biology

“Inspiration for new technologies often can be found in biological systems. A classic example is how plant burrs sticking to an engineer’s dog led to the creation of Velcro.”

“Following in such traditions is Christof Teuscher, an associate professor in Portland State University’s electrical and computer engineering department.”

Abstract: The purpose of this work was to demonstrate the feasibility of building recurrent artificial neural networks with hybrid complementary metal oxide semiconductor (CMOS)/memristor circuits. To do so, we modeled a Hopfield network implementing an analog-to-digital converter (ADC) with up to 8 bits of precision. Major shortcomings affecting the ADC’s precision, such as the non-ideal behavior of CMOS circuitry and the specific limitations of memristors, were investigated and an effective solution was proposed, capitalizing on the in-field programmability of memristors. The theoretical work was validated experimentally by demonstrating the successful operation of a 4-bit ADC circuit implemented with discrete Pt/TiO2−x/Pt memristors and CMOS integrated circuit components.
