A controlled self-oscillating modulator (101) comprising a non-hysteresis comparator (102) for pulse modulation of a switching stage (103), and a voltage feedback loop (104) from the switching stage (103) to the comparator (102), said feedback loop securing stable oscillating conditions by means of at least two poles (105, 106). <??>Such a modulator provides a simple and stable configuration, obviating the need for a separate carrier frequency generator. <IMAGE> |
