Abstract
Embodiments of methods and apparatus for modulating a power source are disclosed. In some embodiments, a method may comprise predicting, by a current control logic, a potential voltage transient on a power supply bus, and modulating, by the current control logic, a current source, based at least in part on said predicting, to control the predicted voltage transient. Additional variants and embodiments may also be disclosed and claimed.
Claims20
A method comprising:
- predicting, by a current control logic, a voltage transient on a power supply bus;
- and
- modulating, by the current control logic, a current source, based at least in part on said predicting, to control the predicted voltage transient.
An apparatus comprising:
- a current control logic configured to control a current source coupled to a power supply bus, the current control logic comprising:
- a current level queue (CLQ) including a plurality of queue entries, each queue entry configured to control the current source during a respective duration of time;
- a default current level register configured to control the current source when the current level queue is disabled;
- and
- a multiplexer to selectively enable either the current level queue or the default current level register and output a current level control signal configured to control a current level of the current source.

A method for controlling a current source, comprising:
- selectively enabling, by a current control logic, either a default current register or a current level queue (CLQ);
- modulating the current source using the default current register, when enabled;
- and
- modulating the current source using the CLQ, when enabled, the CLQ including a plurality of queue entries, each queue entry configured to modulate the current source for a respective duration of time.
