    • An analogue to digital converter for generating a digital representation of the voltage of an input signal, the analogue to digital converter comprising: a plurality of voltage generators, each voltage generator having a control input and being capable of generating an output whose voltage is dependent on a signal applied to the control input; a comparison stage arranged to compare the input signal with one or more outputs of the voltage generators and generate one or more comparator outputs indicative of the result(s) of the comparison(s); and a controller arranged to receive the comparator outputs, the controller being configured to: (i) signal the control inputs of a number V 1 of the voltage generators to cause each of them to generate a respective output, and estimate in dependence on the resulting comparator outputs a number B 1 of bits of the digital representation; and subsequently (ii) signal the control input(s) of a number V 2 of the voltage generators to cause each of them to generate a respective output, and estimate in dependence on the resulting comparator output(s) a number B 2 of bits of the digital representation; wherein V 2 is less than V 1 .
    • 一种用于产生输入信号的电压的数字表示的模数转换器,所述模数转换器包括:多个电压发生器,每个电压发生器具有控制输入并且能够 产生其电压取决于施加于控制输入的信号的输出; 比较级,其被布置为将所述输入信号与所述电压发生器的一个或多个输出进行比较,并且生成指示所述比较的结果的一个或多个比较器输出; 以及布置成接收比较器输出的控制器,所述控制器被配置为:(i)用信号通知所述电压发生器的数量V 1的控制输入以使它们中的每一个产生相应的输出, 并根据得到的比较器输出来估计数字表示的比特的数目B 1; 并且随后(ii)发信号通知电压发生器的数量V 2的控制输入以使它们中的每一个产生相应的输出,并且根据所得到的比较器输出(s )数字表示的数字B 2位; 其中V <2>小于V <1>。
