A novel self-error correction pulse width modulator for a class D amplifier for hearing instruments

In this paper, we propose a novel self-error correction pulse width modulator for a class D amplifier for hearing aid applications. The self-error correction mechanisms based on a master-slave architecture is realized by simple digital circuits and can be easily fabricated in a low cost digital CMOS...

description	In this paper, we propose a novel self-error correction pulse width modulator for a class D amplifier for hearing aid applications. The self-error correction mechanisms based on a master-slave architecture is realized by simple digital circuits and can be easily fabricated in a low cost digital CMOS process. The circuit consumes 24.6 /spl mu/A from a 2.5 V supply. Measurements on the prototype IC shows that the error at zero-input 50% duty cycle is less than 2% and the total harmonic distortion is 3.3%.
