    Abstract: A method of modeling mismatch of capacitors and devices thereof. Unlike methods of only performing a measurement of capacitor mismatch using a floating gate technique, a method of modeling mismatch may include constructing an analog circuit having capacitors including a different ratio and/or size, and/or measuring capacitor mismatch values. A method of modeling mismatch may include extracting modeling parameters by applying measured mismatch values to a mismatch model, and/or calculating actual capacitor mismatch values by applying extracted modeling parameters and/or a ratio and/or size of actual capacitors to be modeled to a mismatch model. It may be possible to detect characteristics of an analog circuit based on calculated and/or actual capacitor mismatch values.

    Abstract translation: 一种对电容器及其器件的不匹配进行建模的方法。 不同于仅使用浮动栅极技术来执行电容器失配测量的方法，对失配进行建模的方法可以包括构建具有不同比率和/或尺寸的电容器和/或测量电容器失配值的模拟电路。 模拟不匹配的方法可以包括通过将被测量的失配值应用于不匹配模型来提取建模参数，和/或通过将提取的建模参数和/或将要建模的实际电容器的比率和/或尺寸应用于 不匹配模型。 可以基于计算的和/或实际的电容器失配值来检测模拟电路的特性。

    Abstract: A low power servo-controlled single clock ramp generator (100) includes a fast switched comparator (102), charge pump (110) and voltage-to-current converter (120) connected to provide a feedback control mechanism under control of a pulse comparison clock signal (pulse_comp) and a reset pulse clock signal (rst_pulse) that are generated from a single input clock signal (clkin) so that there are well defined time intervals between pulses in the pulse comparison clock signal and the reset pulse clock signal, thereby providing a ramp signal (Vramp_out) having a stable, frequency-independent amplitude that is not limited by the reference voltage.
