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 .
Ohhh I see. So the voltage needed to turn on the MOSFET is essentially drawing what it needs from VDD. So the voltage they are talking about that is present across the cap. is the gate to source voltage. What is the drain-source voltage then? The drain is connected to a load, not a voltage source. Is the MOSFET in its linear or sat. mode?
