(US6049201-A)      The circuit arrangement includes a first circuit of several integrators (INl, IN2) connected in series, and a second series circuit of the same amount of further integrators (IN3, IN4). Each integrator of a series circuit receives as input signal a sum of its output signal led back over a first feedback branch, the output signal of the corresponding integrator of the other series circuit, led back over a second feedback branch, and a third signal.    The third signal for the first integrator of a series circuit corresponds to the output signal of the last integrator of the respectively other series circuit, and for the remaining integrators to the output signal of the preceding integrator of the same series circuit. Phase-shifted output signals are thereby produced at the outputs of the individual integrators of the first and second series circuit.    USE -   Especially for smart-power IC in DMOS implementation.    ADVANTAGE -   Provides improved circuit arrangement which reduces power consumption.
