Abstract—A 0.9 V third-order double-sampled delta-sigma
audio ADC is presented. A new method using a combination
of a switched-RC technique and a floating switched-capacitor
double-sampling configuration enabled low-voltage operation
without clock boosting or bootstrapping. A three-level quantizer
with simple dynami
