For an n-channel enhancement MOSFET to be in the ideal saturation region, a common long-channel condition is?

  • AVGS < VTH
  • BVGS > VTH and VDS >= VGS - VTH
  • CVDS = 0 for all VGS
  • DVGS = 0 and VDS < 0 only
Report an error
Correct Answer: B. VGS > VTH and VDS >= VGS - VTH
Explanation: For the standard long-channel model, the device is on when VGS > VTH and enters saturation when VDS is at least the overdrive voltage VGS - VTH.
