INTEGRATED CIRCUIT DEVICE, VOLTAGE REGULATION CIRCUITRY AND METHOD FOR REGULATING A VOLTAGE SUPPLY SIGNAL

摘要

An integrated circuit (IC) device (505) comprises at least one internal voltage regulator (510) arranged to receive a voltage supply signal (525) at a first input (512) thereof, receive a control signal (535) at a second input (514) thereof, regulate the received voltage supply signal (525) in accordance with the received control signal (535), and provide a regulated voltage supply signal (515) at an output (516) thereof. The IC device (505) further comprises at least one voltage regulation power control module (530) operably coupled to the second input (514) of the at least one internal voltage regulator (510) and arranged to provide the control signal (535) thereto. The voltage regulation power control module (530) is further arranged to receive at least one IC device conditional indication (540), and generate the control signal (535) for the at least one internal voltage regulator (510) based at least partly on an available thermal power budget for the IC device (505) corresponding to the at least one IC device conditional indication (540).
