Consider a CMOS inverter with Vdd = 3.3 V. Please be careful with units. The NMOS transistor has the following characteristics. The channel length is 20 nanometers. For NMOS, Oxide thickness = 5 Angstroms, Threshold Voltage = 0.12 V, mobility = 580 cm^2/V-sec, transistor W = 80 nm. For PMOS, all parameters are the same as NMOS except up = 220 cm2/N-sec. (a) (4pts) compute beta_n in units of [A/V^2]. (b) (4pts) compute the resistance Rn of the inverter. (c) (4pts) compute the resistance Rp of the inverter. (d) (4pts) what is the value of noise margin high (NMH) of the inverter? Assume the CMOS inverter has VDD = 3.3 V, VIL = 0.45 V, VIH = 0.92 V, VOL = 0.12 V and VOH = 2.9 V. (e) (4pts) compute the maximum operating frequency of the inverter when the rise and fall times are equal with a value of 0.1 ns each.
