1. one kind provides in response to analog-digital converter (ADC) of the output signal of input signal and turnsChange level, it comprises:

  • Quantizer, this quantizer is connected to reception input signal, and described quantizer comprises;

    Analog-digital converter (ADC), this analog-digital converter is connected to and produces in response to describedThe digitized signal of input signal;

    WithMultiplying digital-to-analog converter (MDAC), this multiplying digital-to-analog converter is connected to generationDescribed output signal is as the quantized signal in response to described digitized signal;

    AndRandom sequence digital to analog converter (RSDAC), this random sequence digital to analog converter is connected toRandom signal is injected to described quantizer, and described random sequence digital to analog converter comprises many alsoThe capacitive branch of townhouse row;

    Wherein capacitive branch separately works during the clock cycle of described quantizer.
