    摘要： The light-emitting driving device can include a driving current generation circuit, a sensing circuit, a PWM signal generation circuit, and a controller. The driving current generation circuit can be connected to a channel terminal of a light-emitting string including a plurality of semiconductor light-emitting elements to generate a driving current supplied to the channel terminal. The sensing circuit is connected to the channel terminal to sense a voltage of the channel terminal. The PWM signal generation circuit can generate a PWM signal that controls the supply of driving current. The controller is connected to the sensing circuit to control at least one or more of the intensity of the driving current and the duty ratio of the PWM signal based on the sensed voltage of the channel terminal.

    摘要： 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.
