Abstract:
An analog-digital converter has multiple feedback, and includes: a capacitor digital-analog converter including a plurality of switches driven by a digital code, and a plurality of capacitors respectively connected to the plurality of switches, wherein the capacitor digital-analog converter is configured to generate a residue voltage based on an analog input voltage and a voltage corresponding to the digital code; first and second feedback capacitors each storing the residue voltage; an integrator configured to generate an integral signal by integrating the residue voltage; first and second comparators respectively configured to generate first and second comparison signals from the integral signal; and a digital logic circuitry configured to receive the first and second comparison signals, and generate a digital output signal from the first and second comparison signals, the digital output signal corresponding to the digital code during a successive approximation register (SAR) analog-digital conversion interval, and the digital output signal corresponding to an average of first and second digital control signals during a delta sigma analog-digital conversion interval, wherein the first and second comparison signals are respectively fed back to the first and second feedback capacitors. The analog-digital converter may be included in various electronic devices, including communication devices.

Claim (Index 11):
The analog digital converter of  claim 1 , wherein the analog-digital converter operates at a Nyquist rate with respect to the analog input voltage.
