| 20110222702 | POWER SUPPLY CIRCUIT INCLUDING VOLTAGE REGULATOR AND HEADPHONE DRIVING CIRCUIT EMPLOYING THE SAME - A power supply circuit including a voltage regulator and a headphone driving circuit employing the same are disclosed. In accordance with the present invention, the power supply circuit may provide stable power supply to the amplifier since the power supply circuit generates the constant voltage +Vreg and the constant voltage −Vreg from +VDD robust to stronger than a power noise, and the balanced signal path for isolating the noise of the input signal to be amplified is not required, thereby simplifying the constitution of the circuit | 09-15-2011 |
| 20110181356 | SWITCHING DEVICE OF DIGITAL AMPLIFIER AND METHOD FOR DRIVING THE SAME - A switching device of a digital amplifier and a method for controlling the same are disclosed. In accordance with the present invention, a linearity is maintain even for a short pulse width since a data signal having a pulse width shorter than a predetermined length. Moreover, when an MLP signal is located at both sides of a compensating signal without overlapping with each other, a problem due to a common mode may be prevented. | 07-28-2011 |
| 20110110533 | MULTIBAND DRC SYSTEM AND METHOD FOR CONTROLLING THE SAME - A multiband DRC system and a method for controlling the same are disclosed. In accordance with the present invention, the system and the method are capable of increasing an overall loudness of an output signal by controlling thresholds and gains of plurality of DRCs included in the multiband DRC system according to frequency bands. | 05-12-2011 |
