H8Q3
"(...)How long must the STORE pulse be on, in picoseconds, to discharge the gate capacitance of Q2 to VIL?"

The values I have:
VS=5.0V, VOH=3.5V, VIH=3.0V, VIL=0.9V, VOL=0.5V

The gate-source capacitance CGS=3.5fF and VT=1.0V.

RON=1800.0Ω, ROFF=100.0MΩ and RPU=18.0kΩ.

Tau gives 77picoseconds
I calculated t, and it gave:
(3.5-4)/(0.5-4) = exp(-t/τ)

exp(-t/τ) = 0.142857142857

-t/τ = ln(0.142857142857) = -1.94591014906

t = T * 1.94591014906
Calculating using 77ps, it should give 149.8, but this value seems to be wrong?
