Abstract: A vibration control device configured to provide a haptic function and control a vibration device driven by a sine wave. The vibration control device includes a sampling frequency signal generator and a sine wave synthesizer. The vibration control device is configured to generate a sampling frequency signal using a clock signal, wherein the sampling frequency signal is related to an operation cycle of a digital filter; and the sine wave synthesizer includes the digital filter. The digital filter is configured to adjust at least one of a cycle of the sine wave and amplitude of the sine wave using the sampling frequency signal and a plurality of coefficients of the digital filter; and generate an adjusted sine wave.

Abstract: An integrated circuit configured to detect a variation in a supply voltage using a phase of an input clock signal dependent on the variation in the supply voltage may include a clock delay circuit configured to delay the input clock signal output from a clock generator using each of different delay cell chains and generate a first delay clock signal and a second delay clock signal; and a phase controller configured to control a first phase so that a difference between the first phase and a second phase is 180 degrees, the first phase being a phase of the first delay clock signal, the second phase being a phase of the second delay clock signal.
