Center of gravity compensation of Class-D amplifier |
摘要 |
In a Class-D Amplifier with PCM (Pulse Code Modulated) input signal, the output pulse width may be adjusted to provide a constant time-voltage-area or the output pulse width may have one of several discrete values to provide a multi-level output system. A fundamental idea of this disclosure is to assure the center of each output pulse is always positioned at the nominal clock or with a fixed delay relative to the nominal clock. Said Class-D Amplifier typically converts the input signal into PDM (Pulse Density Modulated) pulses with a Sigma Delta Modulator and typically drives the output load with an H-Bridge.
