Patent GB-2550243-A (GB)
Title: Class D amplifier circuit
Inventor: JOHN PAUL LESSO
IPC: H03F3/217
Filed: 2014-08-29
Abstract: A modulator 201 controls a Class D output stage 202 based on a modulator input signal Dm to generate an output signal Vout representative of digital input signal Din. The error block 205, which may comprise an ADC 207, generates an error signal E from the input and output signals, and the degree to which the error signal E contributes to the modulator input signal Dm depends on an indication of the amplitude of the input signal Din. The error signal E and the input signal Din are received at first and second inputs 204,206 of a block 203. The error signal is filtered by a loop filter 211, scaled by a variable multiplier 213, then added to the input signal Din. The multiplier 213 scales the feedback signal in dependence on the detected envelope of the input signal. The feedback reduces distortion at high signal levels but is reduced or disabled at low signal levels so that the noise floor depends less on the components of the error block 205 or is independent of these components.
