Delta sigma modulator circuit for an analog-to-digital converter

摘要: In a delta-sigma modulator for an A/D converter modulating analog input signal to produce modulated of digital form, first integrator produces integral indicative the difference between and feedback signal, delay element delays by one sampling period, second output quantizer two-level "1" or "0" depending on whether not is greater than predetermined reference, reference. An produced in accordance with outputs quantizers. The also
