Modulation scheme for filterless switching amplifiers |
摘要 |
A Class-D switching amplifier (20) having a terinary modulation scheme implemented in an H-bridge configuration. The present invention has four states of operation, and achieves increased efficiency and reduced cost by delivering current to the load only when needed, and once delivered, maintaining the current. The Class-D switching amplifier eliminates the need for post amplifier filters.
