Step 1 of 2 5.024P Refer to Figure P5.24 in the text book for the drain and gate connections of MOSFET. (a) The drain and source of the two transistors in the figures are short-circuited. This configuration results in diode-connected transistor model. The voltage V in the figure is, As VDG is VDG ≤V, Hence, the transistor is operating in the saturation region. Write the formula for the drain current, i of a MOSFET in the saturation mode. Here, k' is the process transconductance parameter is the width to length ratio of the channel is the gate-to-source voltage is the threshold voltage Substitute V for Thus, the i-v relationship of the MOSFET is, Step 2 of 2 (b) Write the formula for incremental resistance of a Determine using the i-v relationship of the MOSFET. Thus, the incremental resistance is, 1
