Step 1 of 2 5.010E Refer to Figure E5.10 in the textbook. In the circuit, the gate and drain of transistor are short. So, the gate to source voltage of is, =0.8 V From the circuit, the gate source voltage of transistor is, The transistor is operating at the edge of saturation. Hence, the drain current is, Since transistor is identical to , Substitute 0.4 for 0.72 0.18 µm µm for , 0.8 V for , and 0.5 V for in the equation. = = The transistor is operating at the edge of saturation. Hence, the condition for drain to source voltage of transistor is, Substitute 0.8 V for and 0.5 V for in the equation. = 0.3 V Step 2 of 2 From the circuit, the drain voltage of transistor 0.3 V From the circuit, the resistance is, 1.8-0.3 = Therefore, the resistance is,
