The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is … ...

This paper proposes a novel simplified two-diode model of a photovoltaic (PV) module. The main aim of this study is to represent a PV module as an ideal two-diode model. In order to reduce ...

A band-to-band tunneling injection insulated-gate bipolar transistor (IGBT) featuring a tunnel junction as the collector p-n junction is proposed. The tunnel junction injects not only holes into the n ...

OLED stands for "organic light-emitting diode." QLED (according to Samsung) stands for " q uantum dot LED TV." OLED is a fundamentally different technology from LCD, the major type of TV.
