摘要： A comb filter has series connected integrators to which is fed a digital data stream at a high sampling rate in order to yield a digital data stream at a low sampling rate. The most significant bits of the digital data stream are reset in the first and second integrators, the resetting of the bits in the first integrator being stored in a counter. The counter reading of the counter is fed into the most significant bits of the last integrator at a reset time.

摘要： A comparator circuit is described and contains a comparator, which is provided with an operating point. A montioring circuit suppresses undesired signal bouncing at the output. The bouncing is produced by interferences of the input signal. The monitoring circuit ensures that the circuit output is locked from being switched back to another logical level after switching until the input signal has reached a second threshold value that is higher than the operating point.

摘要： A self-calibrating A/D and D/A converter operating according to the principle of charge redistribution includes a weighted capacitive primary converter network for most significant bits, a subsidiary converter network for bits of lesser significance, and a calibration and correction network. Each of the networks have capacitors. A comparator has an input connected to a node point. The capacitors of the primary converter network are each connected to the node point. A coupling capacitor is connected between the capacitors of the subsidiary converter network and the node point. Another coupling capacitor is connected between the capacitors of the calibration and correction network and the node point.
