摘要:
A Class D amplifier includes a ramp generator configured to generate a first signal and a second signal. Each of the first signal and the second signal oscillate between a minimum value and a maximum value. A signal generator is configured to receive an input signal, the first signal and the second signal. The input signal has a value that is between the minimum value and the maximum value. A signal generator is configured to generate a third signal and a fourth signal. The third signal is generated based on each of the first signal and the second signal transitioning from a value above the value of the input signal to a value below the value of the input signal. The fourth signal is generated based on each of the first signal and the second signal transitioning from a value below the value of the input signal to a value above the value of the input signal. An output stage is configured to drive a load based on the third signal and the fourth signal.

An output regulator includes a plurality of switch arrays. A controller enables selected ones of the plurality of switch arrays in response to a sense signal. The sense signal is based on an output of the output regulator. The controller generates drive signals to control the selected ones of the plurality of switch arrays. The controller adjusts first selected pulses in an output phase of the selected ones of the plurality of switch arrays based on a first pulse width. The controller adjusts second selected pulses in the output phase of the selected ones of the plurality of switch arrays based on a second pulse width greater than or less than the first pulse width.
