Question

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=1850.0Ω, ROFF=110.0MΩ and RPU=10.0kΩ.
The drain of Q1 is still high and the gate of Q2 is at VOL. A STORE pulse comes in and turns on Q3. How long must the STORE pulse be on, in picoseconds, to charge the gate capacitance of Q2 to VOH?

Answer 1

I got it........t=45.55psec
