Claim Text:
1. A loop filter for a data converter in a wireless communication system, the loop filter comprising: first and third resistors sequentially connected to an input end; fourth and second resistors sequentially connected to between an inverting output end and ground; a first capacitor connected to between another end of the first resistor and one end of the fourth resistor; a second capacitor connected to between the one end of the fourth resistor and the output end; a third capacitor connected to between another end of the third resistor and the output end; and an operational amplifier configured to output an operational amplifier response to the output end, wherein an inverting end of the operational amplifier is connected to the other end of the first resistor and a non-inverting end of the operational amplifier is connected to ground.
