    How can the Q-point in a MOSFET can be stabilized against variations in transistor parameters?

    We can use negative feedback that will stabilizes the Q-poin

    For example a resistor from source to ground in a common-source amplifier will provide negative feedback and help stabilize the bias point. If you don't want the resistor to reduce the AC gain, then you can add a bypass capacitor across the resistor.
