Elimination of pop-up noise in class D amplifier |
摘要 |
A class D amplifier includes a driver circuit and a reset circuit. The driver circuit is configured to amplify a PWM (pulse width modulation) signal to generate an amplified PWM signal. The reset circuit applies a predetermined voltage at an input of the driver circuit for a time period after a power supply voltage is applied or before the power supply voltage is deactivated, for eliminating pop-up noise.
