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 3):
The analog digital converter of  claim 2 , wherein the first feedback switch is connected to a ground voltage terminal or a reference voltage terminal to which a reference voltage is applied, in response to the first digital control signal, and\n the second feedback switch is connected to the ground voltage terminal or the reference voltage terminal in response to the second digital control signal.
