A Class-D amplifier architecture to compensate for the instability problem due to the LC filter variation

Class D audio amplifier is widely used in many electronic applications such as automobiles, laptops, and mobile phones. However, electromagnetic interference (EMI) generated by Class-D audio amplifiers frequently requires an external LC filter for suppression. The LC filter itself causes significant nonlinearity. Hence, feedback after LC is...

High Performance Digital-input Class-D Amplifier

Class-D amplifiers have gained popularity for their high-power efficiency, exceeding 90%. Among them, digital-input Class-D amplifiers stand out due to their superior integration and increased immunity to electromagnetic interference (EMI). This project introduces a high-performance digital-input Class-D amplifier, aiming for a dynamic range...
