  • Mixer
    Patent number: 10298176
    Abstract: A mixer includes a transconductance circuit and a mixing circuit. The transconductance circuit includes a capacitor and first and second transconductance modules. The first transconductance module converts a single-ended to-be-shifted voltage signal at a first terminal of the capacitor into a first input current signal. The second transconductance module converts a voltage signal at a second terminal of the capacitor into a second input current signal that cooperates with the first input current signal to constitute a differential input current signal pair. The mixing circuit mixes the differential input current signal pair with a differential oscillatory voltage signal pair to generate a differential mixed voltage signal pair.
    Type: Grant

  • Double frequency-shift keying modulating device
    Patent number: 9853635
    Abstract: A double frequency-shift keying modulating device includes a modulation module. The modulation module receives an oscillating signal and a digital signal, and generates a modulation output signal that has a first frequency. The first frequency is associated with a frequency of the oscillating signal and varies periodically at a second frequency. The second frequency is associated with the digital signal and the frequency of the oscillating signal.
