In the circuit of Fig. P3.42 let VDD 5 10 V, R1 5 R2 5 10 MV, and RD 5 10 kV. (a) Assuming the FET has Vt 5 1.0 V, k 5 0.2 mA/V2 , and 5 0, estimate the FET’s operating point. Hint: note that 10 kV !...

In the circuit of Fig. P3.42 let VDD 5 10 V, R1 5 R2 5 10 MV, and RD 5 10 kV. (a) Assuming the FET has Vt 5 1.0 V, k 5 0.2 mA/V2 , and 5 0, estimate the FET’s operating point. Hint: note that 10 kV ! 10 MV. (b) How is the operating point Q affected if R1 is increased from 10 MV to 20 MV?
