UNDERSHOOT REDUCTION

摘要

In described examples, undershoot reduction circuitry includes a first comparator (210), a second comparator (230), and a controller (218). The first comparator (210) is operable for comparing an indication of a power supply voltage output against a first threshold. The second comparator (230) is operable for comparing an indication of the power supply voltage output against a second threshold. The controller (218) is operable for generating a first power control signal USR to raise the power supply voltage output when the indication of the power supply voltage output has a first slope and crosses the first threshold and to lower the power supply voltage output when the indication of the power supply voltage output has an opposite slope and crosses the second threshold.
