Mosfet subthreshold region
WebThe book “MOS Devices for Low-Voltage and Low-Energy Applications” explores the different transistor options that can be utilized to achieve that goal. It describes in detail the physics and performance of transistors that can be operated at low voltage and consume little power, such as subthreshold operation in bulk transistors, fully WebHowever, subthreshold operation also has its benefits. Firstly, in the subthreshold region, the currents through the transistor are extremely low, orders of magnitude lower than in …

WebDec 1, 2024 · Abstract. In this paper, we propose an n-type double gate junctionless field-effect-transistor using recessed silicon channel. The recessed silicon channel reduces the channel thickness between the underlap regions, results in lowering the number of charge carriers in the silicon channel, and therefore, diminishing the OFF-current in the device.
