Abstract
Presented herein are systems, methods, and apparatus for ultra-low power, low noise switched capacitor radio frequency mixer. In one embodiment, there is described a method for mixing a signal. The method comprises mixing with a mixer, a received signal with a mixing signal to generate a mixed signal. The mixing signal comprises an in-phase component and an out-of-phase component and a desired frequency. The mixed signal comprises a mixed in-phase component and a mixed out-of-phase component. The method also comprises mixing one of the mixed in-phase component and the mixed out-of-phase component based on the mixing signal.
Claims20
A method for mixing a signal, said method comprising:
- mixing with a mixer, a received signal with a mixing signal, said mixing signal comprising an in-phase component and an out-of-phase component and having a desired frequency, to generate a mixed signal, said mixed signal comprising a mixed in-phase component and a mixed out-of-phase component;
- and
- selecting one of the mixed in-phase component and the mixed out-of-phase component based on the mixing signal.
A receiver for mixing a signal, said method comprising:
- a mixer for mixing a received signal with a mixing signal, said mixing signal comprising an in-phase component and an out-of-phase component and having a desired frequency, to generate a mixed signal, said mixed signal comprising a mixed in-phase component and a mixed out-of-phase component;
- and
- wherein said mixer comprising a first switch for selecting one of the mixed in-phase component and the mixed out-of-phase component based on the mixing signal.
A receiver for mixing a signal, said method comprising:
- a mixer operable to mix a received signal with a mixing signal, said mixing signal comprising an in-phase component and an out-of-phase component and having a desired frequency, to generate a mixed signal, said mixed signal comprising a mixed in-phase component and a mixed out-of-phase component;
- and
- wherein said mixer comprising a first switch operable to select one of the mixed in-phase component and the mixed out-of-phase component based on the mixing signal.
