Question

Question 8: The MOSFET in the circuit of Fig. below has Vt = 1 V and kn = 2 mA/V2, and the Early effect can be neglected. a) Find the values of RS and RD that result in the MOSFET operating with an overdrive voltage of 0.5 V and a drain voltage of 1.5 V. What is the resulting ID value? b) If RL is reduced from 15 k?, to 10 k?, what does VD become? c) If RL is disconnected, what does VD become? d) With RL disconnected, what is the largest RD that can be used while the MOSFET is remaining in saturation?

Early effect can be neglected.
a) Find the values of RS and RD that result in the MOSFET
operating with an overdrive voltage of 0.5 V and a drain
voltage of 1.5 V. What is the resulting ID value?
b) If RL is reduced from 15 k?, to 10 k?, what does VD
become?
c) If RL is disconnected, what does VD become?
d) With RL disconnected, what is the largest RD that can be
used while the MOSFET is remaining
in saturation?
