Question 1 A) Please find the following based on the VTC curve of an inverter shown in Figure 1: Figure 1: VTC curve of a CMOS inverter i. VOH, VOL, VIL, VIH, and VM ii. Noise margin iii. Based on the value of the VM, state the condition of this CMOS inverter of whether this is a "good PMOS, bad NMOS" or a "bad PMOS, good NMOS" inverter iv. You're required to redesign the above inverter to have a faster performance. Please indicate on how can this design is achieved with respect to the variation of VM
