WebMOSFET in saturation is: ( )2 (1) iKv V v DDS=− + GS t λ Where the value λ is a MOSFET device parameter with units of 1/V (i.e., V-1). Typically, this value is small (thus the dependence on v DS is slight), ranging from 0.005 to 0.02 V-1. Often, the channel-length modulation parameter λ is expressed as the Early Voltage V WebThe on-state resistance of a MOSFET plays an important role in device selection. For a given application, the on-state resistance (RDS(on)) of a MOSFET at the desired operating temperature is obtained from the normalized on-state resistance versus temperature graph. smalle smartwatch
