    • In one embodiment, an analog to digital converter includes a comparator having a first input, a second input and an output, the first input being coupled to an analog signal, a successive approximation register having a serial input coupled to the output of the comparator, and being configured to generate a plurality of control signals and an N-bit digital value corresponding to the analog signal, and a digital to analog converter having an input coupled to the plurality of control signals, the digital to analog converter further comprising a first, a second, and a third capacitor and a plurality of switches controlled by the plurality of control signals and being configured to couple the first capacitor to the second capacitor and the third capacitor to the second capacitor mutually exclusively to share charge on the first capacitor and charge on the third capacitor with charge on the second capacitor and to generate an analog signal on the second capacitor, the second capacitor being coupled to the second input of the comparator.
    • 在一个实施例中,模数转换器包括具有第一输入,第二输入和输出的比较器,第一输入耦合到模拟信号,逐次逼近寄存器,具有耦合到比较器的输出的串行输入, 并且被配置为产生与所述模拟信号相对应的多个控制信号和N位数字值,以及具有耦合到所述多个控制信号的输入的数模转换器,所述数模转换器还包括第一, 第二电容器和第三电容器以及由所述多个控制信号控制的多个开关,并被配置为将所述第一电容器与所述第二电容器和所述第三电容器相互独立地耦合到所述第二电容器,以在所述第一电容器上共享电荷并充电 在第二电容器上充电的第三电容器上并在第二电容器上产生模拟信号,第二电容器是 耦合到比较器的第二输入端。
