A resistively loaded PMOS inverter circuit is shown in figure Q1. The circuit is implemented with the CD4007UBE PMOS. This is essentially the same circuit as the NMOS inverting logic gate you used in Task 3, but with a PMOS transistor instead. The load resistor RD = 6 kΩ, and the supply voltage is VDD = +5 V. The transistor parameters are µpCox = 55 µA/V2, W = 60 µm, L = 10 µm, and Vt,p = -1. For the purposes of this question ignore the channel length modulation effect, i.e. take λ = 0. a) Calculate VOUT as VIN varies from +5 V to 0 V, with 1 V steps, i.e. for 5 V, 4 V, 3 V, 2 V, 1 V and 0 V. b) What is the maximum DC power dissipated by this circuit?
