Citation | Professor Toumazou made a major advance, whilst working on his PhD, which has led to a radical transformation of analogue signal processing. An insight which, in retrospect, looks simple was to give current rather than voltage the primary role in signal processing schemes. Using transistors in the weak inversion regime, the current mode methodology led to markedly superior performance, most dramatically in reduced power consumption. These advances open up a range of applications, including that of prosthetic implants. Their exploitation has led Toumazou to launch three spin-off companies and to found the Institute of Biomedical Engineering. A recent and exceedingly promising direction of his research is concerned with exploiting the relationship between ionic diffusion characteristics in biochemistry and electron diffusion in semiconductors. The concept is leading to a new class of ultra low-power biosensors with direct applicability to therapeutic systems. |
