TL;DR: In this paper, a DC-DC converter with a hysteresis comparator, a logic unit, a digital-analog converter circuit, and a comparator is described.

TL;DR: In this article, a metal element which promotes crystallization of silicon is disposed in contact with a surface of the amorphous silicon film, and then a thermal processing is performed at a crystallization temperature of the polysilicon film or higher.

TL;DR: In this article, a driving method was proposed to achieve high vertical resolution by starting a second field at a time point when writing of a first field has been completed, while information written in the first field is held.

TL;DR: A low-power normally-off microcontroller unit (NMCU) having state-retention flip-flops using a c-axis aligned crystalline oxide semiconductor (CAAC-OS) such as indium gallium zinc oxide (IGZO) transistors employing a distributed backup and recovery method (distributed method) is fabricated.

TL;DR: In this article, the authors proposed a threshold control circuit for a plurality of TFTs, each having a back gate electrode, a semiconductor active layer, and a gate electrode provided in contact with the active layer through a second gate insulating film.
