Project Summary

Thin-film technologies and devices have made a tremendous progress over the past decades. However, the achievable cutoff frequency of thin-film transistors remains comparatively small, which presents a severe challenge towards the realization of flexible RF electronics. The 10by10.com main objective is to combine advanced metal-oxide thin-film technologies with advanced RF circuit design methodologies to realize a technology breakthrough in high-frequency flexible electronics for wireless communication systems. This technological breakthrough is enabled by a ten-fold improvement of fT through continued device optimization and scaling and yet another ten-fold speed-enhancement through innovative harmonic circuit design techniques beyond the device cutoff frequency. This is achieved by operating the devices well-beyond their cutoff-frequency, either harmonically, or, based on the principle of distributed resistive self-mixing.
