DIGITAL ANALOG CONVERTER ACHIEVING SMALL PEAK VALUE OF DISCHARGING CURRENT AND METHOD OF OPERATING THE SAME

摘要

A digital-to-analog converter capable of performing all discharges within one phase while lowering the peak current and an operation method thereof are disclosed. The digital-to-analog converter includes an amplifier, a charge element connected to one of the input terminals of the amplifier, and a discharge controller for separating the charge voltage of the charge element into a first discharge interval and a second discharge interval. Here, the time constant in the first discharge interval is larger than the time constant in the second discharge interval.
