Problem 6: oxide charge in MOS capacitance Consider the C-V curve of a MOS capacitor in the figure (the solid line). The capacitor area is 6400 m Co-45 pF and C,-5.6pF Cox C1 V. Av If, due to the oxide fixed charge, the C-V curve shifted from the solid line to the dashed line with ΔⅤ 0.05V, what is the charge polarity and the area density (C/em2) of the oxide fixed charge?
