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 .
