    • An interpolation circuit for generating interpolated and extrapolated differential voltages from first and second differential input voltages, comprises first (A) and second (B) differential amplifiers for inputting the first and second differential input voltages, respectively, and for generating a differential output voltage respectively between their inverted output terminal (AN, BN) and their respective non-inverted terminal (AP, BP). The interpolation circuit further comprises a first voltage dividing element array (NT1) disposed between the non-inverted output terminals (AP, BP) of the first and second differential amplifiers, and a second voltage dividing element array (NT2) disposed between the inverted output terminals (AN, BN) of the first and second differential amplifiers, so that the interpolated differential voltages are generated from nodes (n1, n2, n3) in the first voltage dividing element array (NT1) and nodes (n4, n5, n6) in the second voltage dividing element array (NT2). The interpolation circuit further comprises a third voltage dividing element array (NT1) disposed between the inverted output terminal (AN) of the first differential amplifier (A) and the non-inverted output terminal (BP) of the second differential amplifier (B), so that at least a pair of extrapolated differential voltages are generated from nodes (n10, n12) in the third voltage dividing element array (NT3).
    • 为内插电路生成插值和从第一和第二差分输入电压外推差分电压,包括:第一(A)和用于分别输入第一和第二差分输入电压,第二(B)差分放大器,以及用于分别产生差分输出电压 反相输出端(AN,BN)和其respectivement非反相端子(AP,BP)之间的。 内插电路还包括在所述反相输出之间设置在第一和第二差分放大器的非反相输出端(AP,BP)之间布置的第一分压元件阵列(NT1),和一个第二分压元件阵列(NT2) 端子与第一和第二差分放大器的(AN,BN),所以没插值差分电压从节点(N1,N2,N3)中的第一分压元件阵列(NT1)和节点生成(N4,N5,N6) 第二分压元件阵列(NT2)英寸 内插电路还包括一第三分压反相输出端的第一差分放大器的(AN)(A)和所述非反相输出端输出第二差分放大器的(BP)(B)之间设置元件阵列(NT1) 所以也至少一对差分外推电压的从第三分压元件阵列(NT3)中的节点(N10,N12)生成。
