Stability Simulation

The following simulation shows a stability check for the solution previously shown. This design has 64 degrees of phase margin which indicates that the circuit is stable. Generally, the circuit which has more than 45 degrees of phase margin is considered to be stable. For more information on stability analysis checks, see the Op Amps: Stability video series.
