摘要：
A hysteretic DC-DC converter includes an observer circuit configured to generate an observer control signal for injection into the control loop of the converter. The observer circuit may be configured to differentiate the output voltage of the converter to generate a differentiated output voltage. A transconductance amplifier may be configured to output the observer control signal from the differentiated output voltage. The observer control signal may be injected into the control loop in a summing node.
