A Direct Battery Hookup Filterless Pulsewidth Modulation Class D Amplifier With >100 dB PSRR for 100 Hz to 1 kHz, 0.005% THD+N and 16 μV Noise

Due to ever-increasing demand for high-level integration, low power dissipation and high fidelity, Class D amplifier ICs (CDA ICs) need to feature very high power supply rejection ratio (PSRR), very low total harmonic distortion plus noise (THD + N), low output noise, high power-efficiency, low elec...
