Specifically I was wondering the best way to address the negative values I am … Walks through how to find the delay times and rise and fall times of a CMOS inverter loaded with a 1pF capacitor TpHL, 13µs delay TpLH, 3µs delay Does anyone have a clue on what is going one with that part ? Why is there such a discrepancy between the … Download scientific diagram | Propagation delay (tp) versus βratio of circuit under test (CUT).
