Circuit for reducing common mode voltage at input of differential voltage amplifier e.g. class-D audio amplifier, has integrating circuit that comprises differential voltage amplifier and capacitor |
摘要 |
<p>The circuit has an input resistor (R1) and a feedback resistor (R2) and an integrating circuit that comprises a differential voltage amplifier (4) and a capacitor (3). The integrating circuit is powered by reliable supply voltage, where the circuit comprises an analog control circuit (5), digital control circuit (6) and a speaker (9). The analog control circuit controls the class-D amplifier depending on the architecture of the class-D amplifier.</p> |
