Latest Patents
Among his latest patents, two stand out for their innovative designs and functionalities:
1. **Audio Power Amplifier and a Pre-Amplifier Thereof**: This invention features an audio power amplifier that integrates a pre-amplifier, an error amplifier, a comparator, a bridge circuit, and a feedback circuit. Notably, the gain of the pre-amplifier gradually increases when the audio power amplifier is powered on. The comparator generates a Pulse Width Modulation (PWM) signal by comparing a reference signal with the amplified audio signal, allowing the bridge circuit to manage the driving current to a load effectively.
2. **Switching Audio Power Amplifier with De-Noise Function**: This invention enhances audio clarity by integrating a de-noise function. It consists of a first and a second comparator to generate two distinct PWM signals. The logic control unit processes these signals to produce additional PWM outputs, facilitating the adjustment of pulse widths to reduce noise interference. Consequently, the bridge circuit alternates the driving current flow to a load based on the modified PWM signals.
