Patent ID: 8049533

Claim:
A receiver, comprising: a detection unit, detecting whether an input signal group is a noise, and outputting a detection result; and a receiving unit, receiving the input signal group according to a sensitivity, wherein the sensitivity determines the amount of the input signal group that passes through the receiving unit, and the receiving unit dynamically adjusts the sensitivity according to the detection result of the detection unit; wherein the receiving unit comprises: an amplifier, having a first input terminal and a second input terminal receiving the input signal group; a first switch, being turned on/off according to the detection result; a first resistor, the first switch and the first resistor being connected in series between the first input terminal of the amplifier and a first voltage; a second switch, being turned on/off according to the detection result; and a second resistor, the second switch and the second resistor being connected in series between the second input terminal of the amplifier and a second voltage.
