摘要： In one general aspect, a power supply circuit can include a power stage configured to be coupled to a power source and configured to deliver an output voltage to a load circuit, and can include a comparator coupled to the power stage and configured to receive a reference voltage. The power supply circuit can also include a hysteresis control circuit configured to receive at least one of a feedback voltage or a reference voltage and configured to change a hysteresis of the comparator in response to the at least one of the feedback voltage or the reference voltage during a soft-start of the power supply circuit.

摘要： A system and method for a filter tuner is presented. The system comprises a sequential logic, a register, a comparator, a first and second counter, a synchronizing logic, a first and second oscillator, a control logic, and a first and second combinational logic. The method comprises the steps of executing a calibration cycle of a filter tuner, executing a measurement cycle of the filter tuner, and tuning a filter with the filter tuner dependent on a determined cutoff frequency variation.
