A power management approach for a mobile device includes comparing a battery provided power supply voltage to a reference voltage in order to generate an alarm signal. In response to the alarm signal the frequency of an operating clock applied to a system-on-chip is changed.

Power management integrated circuit, power management method, mobile device and clock adjusting method

A system on chip includes a core configured to maintain a clock gating state; a plurality of header switch circuits configured to deliver a supply voltage, which is reduced from an external supply voltage, to the core in response to a plurality of control signals; and a voltage regulator configured to monitor the supply voltage, change logic levels of the plurality of control signals according to a difference level corresponding to a difference between the supply voltage and a preset target voltage, and output the plurality of control signals of which the logic levels have been changed to the plurality of header switch circuits.

System on chip for supplying a voltage

An imaging device includes a light source operating in response to an optical control signal having a predetermined frequency, a sensor including a plurality of pixels, configured to generate an electrical signal in response to a light reception signal output by the light source and reflected from a subject, and a logic circuit configured to generate first raw data of a spatial domain based on the electrical signal, and an image signal processor configured to convert the first raw data into second raw data of a frequency domain, to select low-frequency data of the second raw data within a frequency band lower than a predetermined reference frequency, to apply a predetermined weighting to the low-frequency data to generate weighted data, and to generate a resultant image based on the first raw data and the weighted data.
