Consider an nMOS transistor with VTH = 0.4 V, Kn = 140μA/V2 , length, L = 0.25μm, and width, W = 1.25μm.
(a) Given that VGS = 1V, determine the range of values of VDS for which the device is in the saturation region.
(b) Given that VGS = 1V, determine the range of values of VDS for which the device is in the triode/linar region.
(c) Plot IDS vs VGS for operation in the saturation region. Ignore channel length modulation i.e. assume that λ = 0.
For the following parts, you will try to “size” the transistor to meet your needs i.e. choose its length and/or width.
(d) Keeping the transistor length the same i.e. L = 0.25μm, what width, W, should you choose such that IDS = 252μA when VGS = 1V and VDS = 1.0V. Again, assume that λ = 0.
(e) Keeping the transistor length the same i.e. L = 0.25μm, what width, W, should you choose such that the ON resistance of the transistor (i.e. in the triode region) is ron = 3kΩ. Note: Round the width to the nearest 0.05μm.
