Calculate the capacitance in femtofarads on the output node of an inverter without an external load in a 0.35 μm CMOS process. Use: Wp = 6.5 μm, Wn = 4.1 μm, Lp = Ln = 0.35 μm, Loverlap = 0.1 μm, all diffusion lengths = 1.0 μm, COX = 5 fF/μm^2, Cjn = 0.9 fF/μm^2, Cjp = 1.0 fF/μm^2, Cjswn = 0.2 fF/μm, Cjswp = 0.3 fF/μm Answer: The correct answer is: 27.1
