Circuit for generating a trapezoidal signal with controlled wavefronts, particularly for a converter of satellite receiver

摘要

Embodiments of the invention provide a circuit for generating a trapezoidal signal with controlled wavefronts, particularly for a converter for a satellite receiver, comprising a first oscillator suitable to generate a square-wave signal and a second oscillator which is cascade-connected to the first oscillator, wherein the second oscillator is synchronized with the first oscillator and is suitable to generate a voltage signal which is amplitude-modulated with a trapezoidal modulating signal.
