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.

Abstract: The present invention relates to a slope type analog-to-digital converter. The converter includes: an input switch for switching V_REF voltage, GND voltage, and V_IN voltage; a voltage control unit for adding a V_REF voltage to V_C node voltage output from the input switch; a discharge current source for decreasing the V_C node voltage; a comparing unit for comparing the V_C node voltage and reference voltage; a control unit for controlling an operation of each block; and a counter for counting the number of clocks. The converter can move the operational ranges of the reference voltage and the discharge current source to a positive voltage range by increasing the voltage at the discharge node, and can prevent switch leakage current caused when a voltage level increased at one time is great.

Abstract: A resistor averaging circuit is provided to adjust an averaging resistor value according to an input frequency by obtaining an optimal resistance according to the input frequency and then changing the optimal resistance. A resistor averaging circuit receives a pre-amplifier load resistance(R0) and an output voltage of a pre-amplifier stage. An averaging resistor(R1) is series-connected to the resistor averaging circuit, which outputs an averaged voltage through a BOTTOM terminal. An interpolation block(2) is arranged to be adjacent to the averaging resistor. MOS(Metal Oxide Semiconductor) transistors are series-connected in the interpolation block. The averaging resistor outputs 2^(n-1) optimal resistor values according to an input frequency. Two averaging resistors are series-connected to form one averaging resistor.
