    Abstract: PURPOSE: A slew rate digital converter and a driving method thereof are provided to detect a slew rate in accordance with an RC(Resistance-Capacitance) time constant and convert the slew rate into a digital code, thereby predicting an output terminal time constant of a display device driving IC(Integrated Circuit). CONSTITUTION: A slew rate digital converter(100) includes a clock and pulse generation circuit(110), a reference voltage generation circuit(120), a slew rate detect circuit(130), and a thermometer to binary code encoder circuit(140). The clock and pulse generation circuit generates an input pulse to be applied to an RC time constant circuit part having an RC time constant. The reference voltage generation circuit generates a reference voltage. The slew rate detect circuit outputs detection information including time information, where a feedback pulse inputted through the RC time constant circuit part reaches the reference voltage, by using the input pulse transmitted from the clock and pulse generation circuit, the reference voltage, and a clock generated from the clock and pulse generation circuit. The thermometer to binary code encoder circuit outputs a digital code containing the time information by using the detection information corresponding to the number of clocks.

    Abstract: PURPOSE: A nonlinear single slope AD converter, an image sensor device using the same, a temperature sensor device using the same and a nonlinear slope AD conversion method are provided to acquire reliable nonlinear characteristics by using a digital circuit. CONSTITUTION: A ramp generating part generates a ramp input having a set gradient. A comparator(110) compares an input voltage with the ramp input. A control block(120) transfers information about a comparison time point between the input voltage and the ramp input to a memory unit(140). The control block generates the signal saved in the memory unit or the signal for calling information. The nonlinear counter generates a signal with difference sampling frequencies from inputted clock signals.
