Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: This work proposes a feed-forward PWM-intermodulated-distortion reduction (FFPIDR) technique for closed-loop class-D audio amplifiers. The proposed FFPIDR technique overcomes the trade-off beten out-of-band loop attenuation and in-band loop gain to reduce the PWM-intermodulated distortion while maintaining a high in-band distortion suppression capability without increasing the switching frequency. This results in a high-fidelity and low-quiescent-current audio amplifier suitable for mobile devices. This work is implemented in a   $0.5\;\upmu\text{m}$   CMOS technology, and the measurement result with a 4.2 V supply voltage shows that the proposed FFPIDR technique improves the THD + N by 12 dB when an output por of 340 mW is delivered to an   $8\text{-}\Omega$   load. Compared with other state of the arts, the proposed class-D amplifier achieves 0.0037% THD + N with a quiescent current of 2.4 mA and the smallest chip area of   $0.86\;\text{mm}^2$  , and the measured peak efficiency reaches 92%.
