18.18 Repeat part (a) of the problem in Example 18.2 for the case of inverters that do not use matched QN and QP. Rather, assume that each of the inverters uses (W/L)p = (W/L)n = 130 nm/65 nm. Find the threshold voltage of each inverter. Then determine the value required for the W/L of each of Q5 to Q8 so that the flip-flop switches. (Hint: Refer to Table 16.2.)
VM = 0.46 V; (W/L)5-8 = 1.42
