Threshold voltage calculation of a CMOS gate

  1. May 24, 2017 #1
    Hello all,

    I want to know a suitable way to calculate VTL and VTH of a gate having the gate schematic and constituent transistors SPICE model (NMOS/PMOS models). Is there an easier than doing hand calculations ?

    If you have the schematic and SPICE models, can't you just run a simulation? Do a .dc plot of the input voltage vs the output voltage and you should be able to read VTL and VTH off the plot.
