16.5Consider a CMOS inverter fabricated in a 0.13-µm process for which VDD = 1.2 V, Vtn = −Vtp = 0.4V, μn/μp = 4, and μnCox = 430 µA/V2. In addition, QN and QP have L = 0.13 µm and (W/L)n = 1.0.
(a)Find Wp that results in VM = 0.6 V.
(b)For the matched case in (a), find the values of VOH, VOL, VIH, VIL, NMH, and NML.
(c)For the inverter in (a), find the output resistance in each of its two states.
(d)For a minimum-size inverter for which (W/L)p = (W/L)n = 1.0, find VM.
(a) 0.52 µm; (b) 1.2 V, 0 V, 0.65 V, 0.55 V, 0.55 V, 0.55 V; (c) 2.9 kΩ,2.9 kΩ; (d) 0.53 V
