SIGNAL ATTENUATION NETWORK AND WIRELESS SIGNAL RECEIVER

WIPO Patent Application WO/2019/196119

A1

A signal attenuation network and a wireless signal receiver, relating to the technical field of signal processing. The signal attenuation network comprises a resistor attenuation network and a compensation capacitor. The resistance attenuation network comprises a first differential input end, a first differential output end, a first resistor network, a second resistor network and a third resistor network. The first differential input end comprises a first input end and a second input end. The first differential output end comprises a first output end and a second output end. A first resistance attenuation network is coupled between the first input end and the first output end. The first resistor network is coupled between the first input end and the first output end. The second resistor network is coupled between the second input end and the second output end. The third resistor network is coupled between the first resistor network and the second resistor network. The compensation capacitor is coupled to compensate for the parasitic capacitance of the resistor attenuation network. The described technical solution helps to reduce the influence of parasitic capacitance in a resistance attenuation network and improve the signal processing capabilities.
