Question

pls help me for h8p3?????

Answer 1

More specifically, which question? I'd feel more comfortable in providing hints and/or formulas than just results.

Answer 2

We assume an "ancient" 1μm technology satisfying the static discipline:

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=2150.0Ω, ROFF=115.0MΩ 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?
