A load capacitor of 0.2 pF is connected to the output of a CMOS inverter. Determine the power dissipated in the CMOS inverter for a switching frequency of 10 MHz, for inverter parameters described in (a) Problem 1 and (b) Problem 2.

Problem 1

(a) A CMOS inverter is biased at V_DD = 2.5 V. The transistor parameters are K_n = K_p = 120μA/V², V_TN = 0.4 V, and V_TP = -0.4 V. Calculate and plot the current in the transistors as a function of the input voltage for 0 ≤ v_I ≤ 2.5 V.

(b) Repeat part (a) for V_DD = 1.8 V and 0 ≤ v_I ≤ 1.8 V.

Problem 2

The transistor parameters in the CMOS inverter are V_TN = 0.35 V, V_TP = -0.35 V, = 80μA/V², and = 40μA/V². Let V_DD = 1.8 V.

(a) Determine the peak current in the inverter during a switching cycle for (W/L)_n = 2 and (W/L)_p = 4.

(b) Repeat part (a) for (W/L)_n = 2 and (W/L)_p = 6.
