<p>The integrator is charged by the input signal to a threshold set in a first threshold stage. It is then discharged by a compensation signal whose polarity is opposite to that of the input signal. A switch controlled by the threshold stage controls in turn a unit generating the compensation signal and a summator delivering the digital value corresponding to the input signal. A second threshold stage (SWS2) so controls the switch (ZRZ) when the integrator (INT) output signal has exceeded the threshold set in it, that the compensation signal is reduced.</p> |
