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 device is provided. The integrated circuit device may include a central processing unit (CPU) configured to operate in one of a plurality of modes and a wake-up control circuit configured to control the CPU. The wake-up control circuit may include a clock generator configured to generate an internal clock signal, a multiplexer configured to select a signal from among an external signal and the internal clock signal and to provide the CPU with the selected signal as an operating clock signal, and a controller configured to control the CPU and the clock generator based on the external signal.
