Abstract
An analog-to-digital converter (10) comprises a first and a second sampling capacitor (24, 25), a first integrator (26), a first and a second input switch (31, 32) coupling a first input terminal (11) and a common mode terminal (39) to a first electrode of the first sampling capacitor (24), a third and a fourth input switch (33, 34) coupling a second input terminal (12) and the common mode terminal (39) to a first electrode of the second sampling capacitor (25), a fifth and a sixth input switch (35, 36) coupling a second electrode of the first sampling capacitor (24) to an amplifier common mode terminal (40) and the first integrator input (27), and a seventh and an eighth input switch (37, 38) coupling a second electrode of the second sampling capacitor (25) to the amplifier common mode terminal (40) and the second integrator input (28).
