The ID–VDS of a 1980s vintage (but “ideal”) N-MOSFET is shown in the figure. The VT = 1 V, tox = 100 nm (SiO2) and the source is grounded. (a) What regions of operation do points (1), (2), and (3) correspond to? (b) What is the applied gate voltage? (c) What is the inversion charge density (in electrons per cm2) at the source end of the channel, n(y = 0), and at the drain end of the channel, n(y =...
A common source amplifier circuit based on a single n-channel MOSFET is shown in Figure 4b. Assume that the transconductance gm-60 mS (equivalent to mA/ V) and drain source resistance, os, is so large it may be neglected. 0) Calculate the open circuit voltage gain Av Yout/ Vis. i) The amplifier has a load of 10 k2. Determine the current gain Va. = 12 V 150k 4k3 Vout Vin 200k GND = 0 V Figure 4b a) State the name...
