Abstract
A receiver comprises an input-stage circuit, a filter circuit, an output-stage circuit and a digital control oscillator. The input-stage circuit has a mixer configured for mixing the GFSK signal and a feedback signal to generate an input-stage current signal to the filter circuit. Then the filter circuit filters the input-stage current signal, and converts it into a voltage signal. The output-stage circuit is coupled to the filter circuit, for converting the voltage signal into a digital output data. In addition, the digital control oscillator is coupled to the output-stage circuit, for outputting the feedback signal based on the digital output data.
