Early spannung mosfet

WebEarly versions of MOSFETs were very susceptible to volt-age breakdown due to voltage transients and also had a tendency to turn on under high rates of rise of drain-to-source voltage (dV/dt), both resulting in catastrophic fail-ures. The dV/dt turn-on was due to the inherent parasitic NPN transistor incorporated within the MOSFET, shown WebAs you well know, a basic n-channel MOSFET ( Figure2) consists of two heavily-doped n-type regions, the source and drain, that comprise the main terminals of the device. The gate was made of metal in early incarnations, but is now made of heavily doped polysili-con, while the bulk of the device is p-type and is typically rather lightly doped.

Webthe MOSFET is needed to calculate the midband voltage gain. 9.1 MOSFET Current Mirrors IMPORTANTConcepts 1. A simple MOSFET current mirror is constructed in the same configuration as that of the BJT current mirror. 2. The ratio of output to input current can be determined by the aspect ratios of the two devices. 3. 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 A, which is ...
