摘要: The circuit includes, upstream from a PWM quantizer, that is between the output of sigma-delta modulator and input or PWM-like second ancillary stage any order architecture, with function controlling minimum dynamic modulator. This signal summed to corresponding difference stage, delayed by delay block.
