TINA/Spice/OPA313: Increase Phase Margin

Part Number: OPA313
Other Parts Discussed in Thread: TINA-TI

Tool/software: TINA-TI or Spice Models


I was wondering what ways I could increase my phase margin in the circuit below keeping the same FET (PM is ~27). I know decreasing the gate to source capacitance by picking a different FET helps as does lowering the 1ohm resistor value. I was wondering what other options are available to me? Thank you!
