摘要：Auto-compensation—for compensating voltage regulators generating aregulated output voltage—may be performed dynamically by determining variouscoefficients of a compensation function used in compensating the power regulator, based
at least on assumptions about the structure of the regulator and corresponding filters.At least the DC loop gain and the position of the compensation zeros may be determinedwithout requiring any prior knowledge of the values of the various components of thesystem. The compensator coefficients may be adjusted based on duty-cycle jitterinformation, which may be accurately obtained/measured at a high signal-to-noise ratio.By observing the duty-cycle jitter, the capacitor (equivalent series resistance) may beoptimally compensated by tuning the 0 dB crossover slope of the loop gain. Accordingly,auto-compensation may be performed by measuring the duty-cycle jitter whilemaintaining optimum stability and transient performance.
