Unformatted text preview: and the other resistors are chosen such that V 1 = 8V and V 2 = 7V. What operating mode is the MOSFET in? (c) If R 4 = 500 and R 2 = 10 k , find the values of the resistors R 1 and R 3 such that V 1 is biased at 5V and V 2 is biased at 2V. (d) If R 1 = R 2 = R 3 = 10 k and R 4 is replaced by a capacitor of 1 F and an initial voltage of 0 V. At t = (steady state), what is the value of V 2 ? At t = (steady state), what is the operating mode of the MOSFET? Question 4 (4 points): Find the value of the equivalent small signal resistance R , as indicated below. Your results should be accurate within 1%. V thp = 1 V k p (W/L) = 2 103 A/V 2 = 0 R 1 = 100 k R 2 = 200 k R 3 = 4 k = 99 r o = 4 k g m = 0.1 A/V R 1 10 V R 2 R 3 v S ~ R ?...
