For the inverter circuit in the below figure, let vI go from VDD (high) to 0 V (low) at t = 0. At t = 0+, vO = 0 V. (a) What is tPHL? Express it with τ. Assume VOH = VDD and VOL = 0. (Hint) vo(t) = VOH − (VOH − VOL)e −t/τ (b) If R = 4.7 kΩ, what is the value of the capacitance C that ensures that tPHL = 100 ps?

For the inverter circuit in the below figure, let

v_{I}

go from

V_{D D}

(high) to 0 V (low) at

t = 0

. At

t = 0 +, v_{O} = 0 V

. (a) What is

t_{P H L}

? Express it with

τ

. Assume

V_{O H} = V_{D D}

and

V_{O L} = 0

. (Hint)

v_{o} (t) = V_{O H} - (V_{O H} - V_{O L}) e^{- t / τ}

(b) If

R = 4.7 k Ω

, what is the value of the capacitance

C

that ensures that

t_{PHL} = 100 ps

?
