摘要： Method and arrangement for cyclically AD converting an analog signal with a sampler capacitance and an integrator capacitance, comprising the steps of generating a difference signal multiplied by the ratio of said capacitances from the analog signal and a reference signal, deriving a digital bit from said difference signal, doubling the difference signal multiplied by said ratio, shifting said doubled signal by the reference signal multiplied by said ratio and using the shifted signal as difference signal multiplied by said ratio for the next cycle.
