LADDER-BASED HIGH SPEED SWITCH REGULATOR

摘要

Some embodiments include apparatuses having a switch regulator that includes a first circuit with a first comparator to compare an output of the switch regulator to a first reference voltage, and to provide a control signal to enable or disable a first pass element based on the comparison. The switch regulator includes at least a second circuit having a second comparator to compare an output of the switch regulator to a second reference voltage that is lower than the first reference voltage, and to provide a control signal to enable or disable a second pass element based on the comparison. The switch regulator does not include Miller compensation circuits. Other apparatuses and methods according to other embodiments are described.
