1. An apparatus configured to provide a measurement result value based on a first input signal, wherein the apparatus comprises:
a converter unit configured to provide first values, wherein the first values are based on one of the first input signal; and the first input signal and a second input signal,
wherein a quantization step size of the first values is based on a control signal of the converter unit,
a measurement unit configured to calculate second values, which represent a reference quantity for a plurality of quantization step sizes associated with different values of the control signal, and wherein the measurement unit is further configured to change the control signal between a determination of different first values or a determination of different second values, wherein different first values are provided using different converter quantization step sizes and, wherein different second values are provided using different converter quantization step sizes of the plurality of quantization step sizes; and
a processing unit configured to perform averaging and division operations to provide the measurement result value from a predefined number of first values and a predefined number of second values, wherein an effect of the converter quantization step size on the first values and an effect of the quantization step sizes on the second values at least partially cancels out,
wherein the converter unit and the processing unit are comprised within the measurement unit, wherein the division operations provide an intermediate result, wherein the averaging operations improve a resolution of the intermediate result and provide the measurement result value, and wherein the first and second input signals comprise at least one of: a clock value; and a voltage.
