Abstract:
Thin film transistors are the building blocks for large area electronic systems such as displays, image sensors and other human interface devices where they form the analog front end. There exist many unique applications that desire a system with a high pass/band pass response, for example, ESD protection, event triggers, sensing for biomedical signals in the presence of flicker noise, etc. Such an action is normally achieved using integrated circuits.
In this talk, I will describe our invention – the adaptive dielectric thin film transistor – which is a single device that shows a tunable band pass response (transconductance is high within a frequency band and low outside). The single device with such an ability permits low power design with low layout area thereby increasing the spatial resolution of large area sensors. The talk will be pitched for the general audience – and will walk through the idea from conception through modeling and final experimental verification.
