Abstract
The present invention discloses a chip structure capable of smoothing slope of signal during conversion. And the chip structure is suitable for a DC motor which is embedded in a portable electronic device. The DC motor is for adjusting the focal distance of a digital camera which is installed within the portable electronic device. The chip structure comprises an input terminal, a first converter, a control unit, a second converter, an amplifier circuit and an output terminal. The input terminal is for receiving a first digital signal. The first converter is for converting the first digital signal into an analog signal. The control unit is for elongating the transform time of the analog signal. The amplifier circuit is for amplifying the elongated analog signal. The second converter is for converting the elongated analog signal into a second digital signal. And the output terminal outputs the second digital signal.
