Question

A CMOS inverter is biased at V_DD = 3.3 V. The transistor threshold voltages are V_TN = +0.4 V and V_TP = -0.4 V. Determine the peak current in the inverter and the input voltage at which it occurs for (a) (W/L)_n = 3,(W/L)_p = 7.5;

(b) (W/L)_n = (W/L)_p = 4; (c) (W/L)_n = 3, (W/L)_p = 12.
