Latest Patents
Madhavprasad holds a patent titled "Efficient minimum pulse spread spectrum modulation for filterless class D amplifiers." This innovative method and apparatus enable the use of class D amplifiers without the need for an output filter. The invention ensures both high efficiency and high audio fidelity. By utilizing a classic differential Pulse Width Modulation scheme, the high-frequency carrier is suppressed to achieve ternary modulation. This carrier is then reintroduced as a common mode pulse, modulated in width to provide the necessary output voltage while maintaining a defined threshold. The modulator waveform's frequency can also be modulated on a sample-by-sample basis, allowing the output waveforms' EMI spectrum to be made white at high frequencies. This combination of modulation schemes and spread spectrum behavior allows for the elimination of external filters, showcasing various embodiments of the technology.
