Abstract: A receiver and a receiving method of the receiver such that monolithic integration of multiple receiving channels can be implemented. The receiver includes a zero intermediate frequency channel, performing in-phase/quadrature (IQ) down conversion on a radio frequency signal at a first frequency band using a frequency division or frequency multiplication signal of a first oscillation signal, and a superheterodyne channel, performing down conversion on a radio frequency signal at a second frequency band using the frequency division or frequency multiplication signal of the first oscillation signal, where the first frequency band is different from the second frequency band. The zero intermediate frequency channel and the superheterodyne channel use a same oscillation signal or a same frequency division or frequency multiplication signal of the oscillation signal, thereby monolithic integration of multiple receiving channels can be implemented.

Abstract: An oscillator used in RF system. The oscillator includes a pair of transistors to which source terminals are interconnected and to which drain and gate terminals are coupled by a positive feedback loop comprising an oscillator tank, wherein the source terminals of the transistors are connected to a current source configured to control physical parameters of the oscillator.
