Challenge Problems
Push your limits with challenges.
Question 1
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?
π‘ Hint: Investigate the state of the PMOS concerning VGS and Vth.
Question 2
If a PMOS transistor's drain current is calculated using ID = 1/2 Kp (VSG - |Vth|)^2 (1 + Ξ»VDS), how would increasing VDS impact the current assuming Ξ» is significant?
π‘ Hint: Focus on how the parameter Ξ» interacts with VDS in the equation.
