Title:
MODULATION DEVICE FOR CLASS D SWITCHING AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2013/018950
Kind Code:
A1
Abstract:
According to a modulation device for a class D switching amplifier of a desirable embodiment of the present invention, the modulation device for a class D switching amplifier is capable of reducing power consumption of an EMI of an output end and a gate driver end in a zero input signal. The modulation device for a class D switching amplifier of a desirable embodiment of the present invention includes a control unit for detecting and outputting a control signal which is a common signal component of a first modulation signal modulated by using a first input signal and a second modulation signal modulated by using a second input signal; and is characterized by feedback of a first output signal, a second output signal and a common output signal outputted by using the first modulation signal, the second modulation signal and the control signal through an input of the modulation device.
