A PMOS transistor is connected in a CMOS inverter, with a threshold voltage of -2V. If the gate-source voltage is -3V and VDS is sufficient to ensure saturation, what will be the state of the PMOS transistor?
💡 Hint: Investigate the state of the PMOS concerning VGS and Vth.
If a PMOS transistor's drain current is calculated using ID = 1/2 Kp (VSG - |Vth|)^2 (1 + λVDS), how would increasing VDS impact the current assuming λ is significant?
💡 Hint: Focus on how the parameter λ interacts with VDS in the equation.
