Abstract
An apparatus is provided which includes: a first set of devices which is digitally controlled by a first feedback loop that includes a first comparator; and a second set of devices which is controlled by an analog circuitry which is part of a second feedback loop that includes an amplifier, wherein the first set of devices is coupled in parallel to the second set of devices.
Claims24
An apparatus comprising:
- a first set of devices digitally controlled by a first feedback loop that includes a comparator;
- and
- a second set of devices controlled by an analog circuitry which is part of a second feedback loop that includes an amplifier, wherein the first set of devices is coupled in parallel to the second set of devices.
An apparatus comprising:
- a digital low dropout (LDO) coupled to an input power supply node and an output power supply node;
- and
- a set of analog LDOs coupled in parallel to the digital LDO, wherein at least one analog LDO of the set is always on.
A system comprising:
- a memory;
- a processor coupled to the memory, wherein the processor includes a processor core which is powered by a supply generator, wherein the supply generator comprises:
- a first set of devices digitally controlled by a first feedback loop that includes a comparator;
- and
- a second set of devices controlled by an analog circuitry, which is part of a second feedback loop that includes an amplifier, wherein the first set of devices is coupled in parallel to the second set of devices;
- and
- a wireless interface to allow the processor to communicate with another device.
4 more elements
An apparatus comprising:
- a digital low dropout (LDO) coupled to an input power supply node and an output power supply node;
- and
- a set of analog LDOs coupled in parallel to the digital LDO, wherein the digital LDO and the set of analog LDOs are controllable to obtain a target Power Supply Rejection Ratio (PSRR).
