    Abstract: An integrated circuit includes a highest class core circuit that has a positive power supply terminal connected to a positive power supply terminal of an external power source, and is configured to receive a first supply voltage which is at least a portion of a an input supply voltage that is provided from the external power source based on an operation throughput; and a lowest class core circuit that has a positive power supply terminal connected to a negative power supply terminal of an adjacent upper class core circuit, has a negative power supply terminal connected to a negative power supply terminal of the external power source, and is configured to receive a second supply voltage which is at least a portion of a part of the input supply voltage that excludes the first supply voltage.

    Abstract: A filter system includes a first resonator having a first resonant frequency, and a second resonator having a second resonant frequency different from the first resonant frequency, and electrically connected to the first resonator. A first response characteristic of the first resonator and a second response characteristic of the second resonator with respect to a frequency include a first section in which a first phase of the first resonator is equal to a second phase of the second resonator, and a second section in which the first phase is different from the second phase by 180 degrees. A first electrode of the first resonator is reversely connected to a second electrode of the second resonator.

    Abstract: A compact directional acoustic sensor having an improved signal-to-noise ratio is disclosed. The disclosed directional acoustic sensor includes a first sensing device configured to generate different output gains based on different input directions of external energy, and configured to generate at least one first output signal having a first polarity based on external energy received from an input direction; a second sensing device configured to generate different output gains based on different input directions of external energy, and configured to generate at least one second output signal having a second polarity, that is different than the first polarity, based on the external energy received from the input direction; and at least one signal processor configured to generate at least one final output signal based on the at least one first output signal and the at least one second output signal.
