    • A method of gain calibration of an ADC stage is provided. The method includes steps of receiving an input analog signal, converting the input analog signal into an m-bit digital signal by means of an analog to digital converter, generating a calibration signal by means of a random number generator, adding the calibration signal to the m-bit digital signal to produce an adjusted m-bit digital signal, converting the adjusted m-bit digital signal into an adjusted partial analog signal by means of a digital to analogue converter, subtracting the partial analog signal from the input analog signal, to produce a residual analog signal, amplifying the residual analog signal. The the calibration signal may take any one of three values and may be constrained to one of only two of these three values. An ADC stage adapted to operate according to the method is also provided.
    • 提供了ADC级的增益校准方法。 该方法包括以下步骤:接收输入模拟信号,借助于模数转换器将输入模拟信号转换成m位数字信号,通过随机数发生器产生校准信号,将校准信号加到 m比特数字信号,以产生经调整的m位数字信号,通过数模转换器将调整后的m位数字信号转换成调整后的部分模拟信号,从输入模拟信号中减去部分模拟信号, 产生残留模拟信号,放大残留的模拟信号。 校准信号可以采用三个值中的任何一个,并且可以被限制为这三个值中的仅两个之一。 还提供了适于根据该方法操作的ADC级。

    • A method of gain calibration of an ADC stage is disclosed. The method comprises receiving an input analog signal, converting the input analog signal into an m-bit digital signal by means of an analog to digital converter, generating a calibration signal by means of a random number generator, adding the calibration signal to the m-bit digital signal to produce an adjusted m-bit digital signal, converting the adjusted m-bit digital signal into an adjusted partial analog signal by means of a digital to analogue converter, subtracting the partial analog signal from the input analog signal, to produce a residual analog signal, amplifying the residual analog signal. The method is characterised in that the calibration signal may take any one of three values. In a preferred embodiment, the calibration is constrained to one of only two of these three values, when the input signal is in an outermost sub-range. An ADC stage adapted to operate according to the method is also disclosed.
