Abstract
We present flexible common source and cascode amplifiers fabricated on a free-standing plastic foil, using amorphous-Indium-Gallium-Zinc-Oxide (a-IGZO) TFTs with minimum channel lengths of 2.5 μm. Amplifiers are operated at a supply voltage VDD of 5 V, and exhibit maximum cutoff frequencies fC of 1.2 MHz. The circuits stay fully operational while bent to a tensile radius of 5 mm, and after 1000 cycles of repeated bending and re-flattening. To our knowledge, these are the fastest flexible oxide semiconductor based amplifiers.
