WebThe op amp in your circuit is driving an almost entirely capacitive load - the MOSFET's gate. There are many possible ways to correct this using just a well-placed resistor or a capacitor. It might be best to use a series resistor or a parallel RC shunt, or a feedback RC pair - it all depends on the particular circuit in question.

The capacitance interacts with the open-loop output impedance, R O, of the amplifier to introduce a pole, fp O1, in the amplifier’s open-loop gain curve, as shown in Figure 3. This pole causes excessive phase shift in the feedback loop, severely degrading phase margin. slow cooker asian soup

resistive loading vs. capacitive loading for op amp
