Question
(a) What is the output current IO in the circuit
shown if −VEE = −10 V and
R = 20 ohm? Assume that the MOSFET is saturated.
(b) What is the minimum voltage VDD
needed to saturate the MOSFET if VTN = 2.5 V
and K'n = 0.25 A/V2. (c) What must be the power
dissipation ratings of resistor R and the FET.
Expert Solution
Step 1
a) The circuit can be modified for better understanding is given as
- The voltage at non inverting terminal is given as 0V hence by virtual ground concept the voltage as Inverting terminal is given as 0V
- The current I can be found as
Step 2
b)
The drain current equation in case of saturation is given as
Thus minimum voltage of VDD should be 4.5 V for the MOSFET to be in saturation.
