Abstract:
A delta-sigma modulator may comprise a loop filter for integrating and outputting a difference between an input signal and an analog signal; a quantizer for quantizing and outputting a signal output from the loop filter; and a digital-to-analog converter (DAC) for outputting the analog signal by digital-to-analog converting a signal output from the quantizer. Also, the loop filter may comprise an operational amplifier; and a circuit including at least one capacitor, at least one resistor, and at least one switch which are connected to the operational amplifier. Also, signal transfer characteristics of the loop filter satisfy a third-order transfer function or a second-order transfer function by turning on or off the at least one switch.

Claim (Index 9):
The loop filter according to  claim 5 , wherein at least one of the first resistor, the sixth resistor, and the seventh resistor is a variable resistor, and a loop gain is changed by adjusting the at least one of the first resistor, the sixth resistor, and the seventh resistor.
