Voltage droop detection and frequency recovery

A method comprising:

• detecting a voltage droop onset at a voltage droop detector comparator circuit;
• generating a voltage droop indication signal at the voltage droop detector comparator circuit in response to detecting the voltage droop onset;
• generating a plurality of sequential frequency slowdown capacitance values at an asynchronous capacitance circuit based on the voltage droop indication signal;
• and
• generating a plurality of output oscillation values at an electronic oscillator, each of the plurality of output oscillation values based on a corresponding value within the plurality of sequential frequency slowdown capacitance values, the plurality of output oscillation values providing a gradual frequency recovery from a lower voltage droop frequency to a steady-state frequency.

An apparatus comprising:

• a voltage droop detector comparator circuit;
• an asynchronous capacitance circuit coupled to the voltage droop detector comparator circuit;
• and
• an electronic oscillator coupled to the asynchronous capacitance circuit, the electronic oscillator to provide a gradual frequency recovery from a lower voltage droop frequency to a steady-state frequency.
