*MAX4685 TEST CIRCUIT FILE TO MEASURE
*NC_OFF AND NO_OFF CAPACITANCE
*TO CALCULATE NC_OFF CAPACITANCE FOLLOW THE STEPS GIVEN BELOW:
*1. PLOT I(VNC1) vs. FREQUENCY
*2. MEASURE I(VNC1) AT 1MHz
*3. USE THE EQUATION, C(NC_OFF) = I(VNC1)@1MHz/(2*3.142*1E6)
*TO CALCULATE NO_OFF CAPACITANCE FOLLOW THE STEPS GIVEN BELOW:
*1. PLOT I(VNO2) vs. FREQUENCY
*2. MEASURE I(VNO2) AT 1MHz
*3. USE THE EQUATION, C(NO_OFF) = I(VNO2)@1MHz/(2*3.142*1E6)
