Instruction: Answer the following questions using the LTSPICE. Submit the LTSPICE for verification (Lastname_Exam1Part2.asc). Build an inverter in LTSPICE with: $VDD=3\mathrm{V},\mathrm{Ln}=\mathrm{Lp}=10\mathrm{um},\mathrm{Wn}=40\mathrm{um},\mathrm{Wp}=90\mathrm{um}$, and $V$ in as a pulse with $VL=0,VH=3,td=0,tr=1p,tf=1p$, ton $=1u$, and $T=2u$. (Note: The specifications of Vin can be adjusted, if necessary.) Use the given device models in the simulation: .MODEL NMOS NMOS LEVEL $=1$ VTO $=0.7\mathrm{KP}=110\mathrm{U}$ LAMBDA $=0.04\mathrm{GAMMA}=0.40\mathrm{PHI}=0.7$ .MODEL PMOS PMOS LEVEL $=1$ VTO $=-0.7\mathrm{KP}=50\mathrm{U}$ LAMBDA $=0.05$ GAMMA $=0.57\mathrm{PHI}=0.8$ Run a simulation (.TRAN $4\mathrm{U}$ ) and measure the following: (a) output signal rise time, tr, (b) output signal fall time, tf, (c) input-to-output signal low-to-high propagation delay, tpLH, and (d) input-to-output signal high-to-low propagation delay, tpHL.
