Abstract
Methods and apparatus are described for reducing or eliminating break-before-make distortion in switching amplifiers. A switching amplifier has an input stage for generating a switching signal. Break-before-make distortion compensation circuitry alters the switching signal. Break-before-make generator circuitry generates two drive signals from the altered switching signal. A power stage includes two switches which are alternately driven by the two drive signals. Break-before-make distortion detection circuitry detects a distortion pattern at the power stage output node and controls the break-before-make distortion compensation circuitry to alter the switching signal in response to the distortion pattern detected to thereby eliminate at least some break-before-make distortion.
