Trajectory prediction and error estimation of non-Foster circuit TE curve. Top: Actual TE trajectory in dark blue and the predicted trajectory and its 95% confidence interval in green. The predicted trajectory stays close to the actual trajectory. The magenta diamonds indicate that the actual trajectory points appear outside the 95% confidence interval of the prediction, which is used as early detection of synchronization, or circuits entering the unstable region. Bottom: non-Foster circuits in voltage.
