For the NMOS inverter with depletion load. Assume VDD = 5 V, VTD = 1 V, KD = 81.1 μA/V2, VTL = −2 V and KL = 27.8 μA/V2. If VOH = 5 V, VOL = 0.17 V and the input is switched from high to low logic at t = 0, then for t > 0, the charging current (μA) for the load capacitor when Vo = 2.4 is a. 101.19 b. 1089.98 c. 111.20 d. 1297.60
