4 cards from this section. Quick, good the night before a test.
What happens when VGS is above Vth for a PMOS transistor?
Think about the threshold condition.
What type of channel do PMOS transistors use?
Recall the type designation of the PMOS transistor.
What is the threshold voltage for a PMOS transistor?
Think about how p-type devices operate.
In which region does a PMOS transistor conduct current linearly?
Look back at the operation regions.
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?
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?
Focus on how the parameter λ interacts with VDS in the equation.
