Dynamic switching frequency control for a digital switching amplifier |
摘要 |
A switching amplifier is described which includes an input stage having a first node associated therewith and a power stage having a second node associated therewith. An actual loop delay is defined with reference to the first and second nodes. Delay detection circuitry compares the actual loop delay to a reference loop delay. A dynamic delay line controlled by the delay detection circuitry controls the actual loop delay to correspond to the reference loop delay.
