Crossover distortion in power amplifiers
WebMar 10, 2015 · This flat spot is crossover distortion. It happens due to the circuit being non-linear when it is "crossing over" between using the top the transistor to drive the … As with most kinds of distortion, another way in which crossover distortion can be reduced is through the use of feedback. By comparing the output to the desired output, and adjusting the input to correct for any error, we can significantly reduce distortion. This may be done with an operational amplifier, as shown below, or with a discrete circuit.
