Abstract |
AB |
[EN] A switching amplifier includes a modulator, which includes a pulse generator. The pulse generator generates positive and negative pulses, in response to an input signal, and the frequency of the negative pulses can be controlled independently of the frequency of the positive pulses. The positive pulses and negative pulses are combined to form a composite pulse stream, which can be low-pass filtered such that the filter output is an amplified version of the input signal.
[FR] L'invention concerne un amplificateur de commutation comprenant un modulateur, équipé d'un générateur d'impulsions. Le générateur d'impulsions génère des impulsions positives et négatives en réponse à un signal d'entrée et la fréquence des impulsions négatives peut être réglée indépendamment de la fréquence des impulsions positives. Les impulsions positives et négatives sont combinées pour former un flux d'impulsions composite pouvant être soumis à un filtrage passe-bas de manière que la sortie du filtre constitue une version amplifiée du signal d'entrée. |
