Some embodiments include apparatuses and methods using capacitor circuitry to sample a value of an input signal; comparators to compare the value of the input signal with a range of voltage values andprovide comparison results; successive approximation register (SAR) logic circuitry to generate first bits and second bits based on the comparison results; and circuitry to calculate an average valueof a value of the second bits and a value of bits of a portion of the first bits, and to generate output bits representing the value of the input signal, the output bits including bits generated based on the average value. 些实施例包括设备和方法，其使用电容器电路对输入信号的值进行采样；使用比较器将输入信号的值与系列电压值进行比较，并提供比较结果；使用逐次逼近寄存器(SAR)逻辑电路基于比较结果生成第位和第二位；以及使用电路计算第二位的值与第位的部分位的值的平均值，并且生成表示输入信号的值的输出位，该输出位包括基于平均值生成的位。
