mean. n. 1. Something having a position, quality, or condition midway between extremes; a medium. 2. A number that typifies a set of numbers, such as a geometric mean or an arithmetic mean.he antilog of the mean of the logarithm of the calculated values, the same as the n th root of the product of the values. It is often a more useful mean for growth curves.
Threshold Voltage Threshold voltage, V, is defined as the minimum gate bias which can form a conducting channel between the source and drain. For power MOSFETs, it is usually measured at the drain-source current of 250uA. Gate oxide thickness and doping concentration of the channel can be used to control the V .
MOSFET. A metal oxide field-effect transistor, or MOSFET, is an electronic component that amplifies and switches electrical currents. In the 1970s, electronics manufacturers made them with metal oxides, but more recently, silicon has been the material of choice.hotos.com/Photos.com/Getty Images. MOSFET audio power amplifiers deliver decent sound quality with high efficiency at power levels exceeding 1 kilowatt. MOSFET, specifically, is a type of transistor that works well as a switch and is widely used in computers.
