  • Publication number: 20240195429
    Abstract: The present disclosure relates to an analog-to-digital converter that reduces power consumption by reducing an operating current and a semiconductor device having the same. The analog-to-digital converter includes a capacitor-resistor (C-R) hybrid digital-to-analog converter (DAC) circuit including a capacitor digital-to-analog converter (CDAC) circuit including a capacitor array, and a resistor digital-to-analog converter (RDAC) circuit including a resistor string, a comparator that compares an output voltage of the C-R hybrid DAC circuit with a common mode voltage and outputs a comparison result, and a control logic circuit that controls a switch operation of the C-R hybrid DAC circuit and the comparison operation of the comparator using a driving clock with a duty cycle greater than a duty cycle of the first clock based on a system clock, and determines each bit of digital data by receiving the comparison result of the comparator.

  • Patent number: 12006757
    Abstract: Disclosed herein is an over-slam bumper for a vehicle. The over-slam bumper includes: a bumper unit (100) of which an end portion protrudes toward a door to absorb shock generated between a vehicle body and the door; and a mounting unit (200) coupled with the bumper unit (100) to fix the bumper unit to the vehicle body, wherein the bumper unit (100) includes: an elastic part for absorbing shock generated when getting in contact with the door; and a coupling part (116) connected to the elastic part and coupled with the mounting unit (200). The elastic part includes a buckling part (111) for absorbing shock by buckling; a compression part (130) for absorbing shock by compression; and an elastic air compression part for absorbing shock by sealing the inside air to compress inside air.
